    WEAPONS AND EXPLOSIVE DETECTOR AND DETECTION METHOD
    DESCRIPTION
    The present invention relates to a weapon and explosives detector a method for the detection of weapons and explosives. More specifically, the present invention relates to the detection of FDI (Improvised Explosive Device, improvised explosive device) to the passage of vehicles, detection of lapa bombs, detection of land mines and / or detection of urban and zulo weapons.
    STATE OF THE TECHNIQUE
    In the state of the art the document WO2015 / 044487 describes an electrostatic field sensor and an indoor security system that is capable of measuring electrostatic fields and their variations along a metallic conductor that acts as an antenna or probe of captation. This probe is connected to an electronic circuit capable of decoding these changes in the electrostatic field around the metallic conductor of the antenna.
    This system allows the perturbation to be measured by means of a single antenna and, from there, to infer the presence of a person, distinguishing it from an animal or thing through the measurement of the disturbance itself in a single antenna. This system is intended as a preventive alarm detector, by proximity, by detecting a disturbance in the emission of the only electrode.
    However, this system is intended as a security and alarm detector system, but does not describe an explosives and weapons detector, for which it would be necessary to modify the system described in WO2015 / 044487 so that it can be used in an environment of constant threat and with strong countermeasures from the enemy.
    In the state of the art systems for the detection of FDI are described, for example, documents US9036985 and US2015 / 114144.
    On the other hand, document US2014 / 077993 describes an orientable block, in which at least antennas of transmission and reception of means for the detection of improvised explosive devices are mounted, which are directed in such a way as to illuminate the

    minus one and the same area of space, and a detection confirmation camera that is directed towards the area illuminated by these transmitting and receiving antennas in such a way as to be able to form an image of this area, as well as means to control the orientation of said orientable block, which cause a displacement of said block in a manner such as to generate an exploration of a part of the space by said detection means.
    Also, US2009 / 182525 describes a method that can include the detection of FDI by detecting the presence of a non-linear electronic component of an FDI. The presence of a non-linear electronic component of the IED can be detected by illuminating the device with a high power microwave signal that contains a plurality of radio frequencies of the electromagnetic radiation and the reception of sum and / or difference frequency components that they are produced by interaction of the lighting of the signals with a non-linear and subsequently re-irradiated FDI component.
    In general, against the state of the art, the use of an electrostatic sensor that detects the disturbances of the electrostatic field by means of a single antenna, configured as an electrode arranged in such a way that it greatly simplifies the detection structure, since with a single antenna It is possible to detect and characterize any perturbation regardless of the composition of the threat (regardless of the material with which it is composed) allowing greater security and reliability in the detection of threats in an environment that, by definition, is changing and requires a fast, efficient, low-cost detection system that allows friend / enemy identification on the battlefield and immune to electronic countermeasures that can be established by the enemy.
    DESCRIPTION OF THE INVENTION
    The object of the present invention is a weapon and explosives detector and a method for the detection of weapons and explosives. More specifically, the present invention relates to the detection of FDI (Improvised Explosive Device, improvised explosive device) to the passage of vehicles, detection of barnacle bombs in said vehicles, detection of land mines and / or detection of weapons in zulos or other places.
    The weapon and explosives detector and method of the invention is more precise (it can detect any disturbance generated by any threat) and simple to implement (it is based on the use of at least one antenna consisting of a single emitter-receiver electrode) that those described in the state of the art, so it is implemented by measuring the disturbances

    produced in an electrostatic field due to the presence of any object in its vicinity.
    The weapon and explosive detector of the invention comprises, at least, an electrostatic sensor capable of measuring the disturbances generated by people, objects or animals around an antenna that is, in turn, emitter of an electrostatic field and that detects the disturbances that occur in the emitted field. This antenna, which consists of a single electrode, emits the electrostatic field in a directed way, that is, it can emit towards a portion of the surrounding space and not omnidirectionally, shielding the unwanted emission part. That is why the arrangement of this antenna is different in each application since each antenna is autonomous to detect a disturbance in the electrostatic field generated around it, even if they are connected to a single sensor. Thanks to the arrangement of the antenna or antennas it will be possible to define a physical space “covered” by the emitted field, depending on the physical structure where it is implemented (modifying the disposition of the different elements for each particular case) without any limitation and very simple way.
    These advantages are achieved with the various aspects described in the independent claims and which are incorporated herein by reference. Other particular embodiments of the invention are described in the dependent claims and are also incorporated herein by reference.
    Thanks to the weapons and explosives detector described in these attached claims, a weapons and explosives detector and method for the detection of weapons and explosives are obtained. More specifically, the present invention relates to the detection of FDI (Improvised Explosive Device, improvised explosive device) to the passage of vehicles, detection of lapa bombs, detection of land mines and / or detection of weapons, by detecting the approach of the person and / or characterization of a foreign element that can be considered in itself a threat.
    Throughout the description and the claims the word "comprises" and its variants are not intended to exclude other technical characteristics, additives, components or steps. For those skilled in the art, other objects, advantages and characteristics of the invention will be derived partly from the description and partly from the practice of the invention. The following examples and drawings are provided by way of illustration, and are not intended to restrict the present invention. In addition, the present invention covers all possible combinations of particular and preferred embodiments indicated herein.

    EXHIBITION OF A DETAILED MODE OF EMBODIMENT OF THE INVENTION
    An object of the invention is a weapon and explosives detector comprising different practical embodiments, as shown below each of the particular embodiments of the parts that make up the weapons and explosives detector object of the invention is detailed.
    The electrostatic field sensor (10) is a solution based on the sensor described in WO2015 / 044487 but improved for use as a weapon and explosives detector.
    However, an alternative embodiment to said sensor is described in Figure 1. As can be seen in said figure 1, the electrostatic field sensor (10) comprises an antenna (11) consisting of a single electrode that is, at the same time, emitter and receiver (emitter-receiver electrode) and which is the antenna (11) used in each and every one of the embodiments proposed in the present invention, although in different physical configurations and connectivity that allow to improve its functionality. It must be taken into account that in some embodiments, several antennas can coexist in parallel, although, each of them retains the particularity of being a transmitter and receiver at the same time.
    However, the controlled electrostatic field sensor (10) also comprises a circuit
    5

    of generation and measurement of fields, preferably a tuning circuit with a working frequency of less than 5 MHz comprising an RLC circuit and a phase stabilizing circuit. The signal received in the antenna, after the measurement, passes through a filtering stage and, subsequently, said signal passes to an analog-digital converter, which in turn is connected to a processor configured to detect the variations of the electrostatic field, establishing a three-dimensional map with said variations, being able to determine the volume and density of the object that generated said variation. This processor, in turn, is connected to a radio frequency circuit that emits an encrypted signal to a control device (100), which is external to the sensor itself (10) as can also be seen in Figure 5. The circuit is completed with a data storage memory.
    Mine detection
    As can be seen in figure 2, there are two possible devices for the detection of mines, a vehicle adapted for the detection of mines (figure 2a) and a device for individual or manual use (figure 2b).
    It is known to those skilled in the art that there are different types of land mines that are generally classified into two large groups: anti-tank mines and anti-personnel mines.
    The anti-tank mines, in turn, are of different types depending on their type of activation, although the most common are those of magnetic activation, which are activated by proximity of the vehicle and those of activation by contact, either when touched or when touched. relieve pressure on the activation mechanism.
    On the other hand, antipersonnel mines are generally activated by contact or pressure on them and their fabrication materials vary considerably, being preferably of plastic material, to avoid their detection or of the oldest metal material.
    Therefore, the variety of threats means that the means to detect such threats also have to be flexible enough to detect any material in any position. For this, the vehicle for the detection of mines comprises a front implement that incorporates at least one antenna (11) connected with at least one sensor (10).
    In a preferred embodiment, shown in Figure 2a, this front implement simply consists of at least one beam (1) fixed to the vehicle (2) so that it can be retractable
    5
    10

    35
    or telescopic since its deployment is only necessary in case of combat and not, for example, when the vehicle is in the base or quartering.
    In the embodiment of Figure 2a the preferred realization is shown where the perturbation (1) forms an angle (a) of 45 ° with the front of the vehicle (2) since in this way it is possible in a single sweep to control both the road as the shoulders or ditches of it. However, other solutions of the beam forming other angles with the front of the vehicle can be contemplated depending on each specific use or application.
    Inside the beam (1) the antenna (11) will be housed in such a way that an electrostatic field (3) is created around the beam (1) and directed in the lower direction, by shielding the upper part of the pertiga (1) (see detail 2c, section A-A 'front of the pertiga). With this, the field is exclusively oriented towards the ground, which is the area where the anti-tank or anti-personnel mines are buried. Similarly, the figure shows how there is also a perimeter antenna (11 ’) that allows the creation of a second perimeter field (3’) with respect to the vehicle itself (2).
    Similarly, a manual device for infantry use is shown in Figure 2b, consisting essentially of a light beam (1a) of a light material, for example a plastic or other electrically non-conductive polymer and which can be equally extensible to facilitate individual use As in the beam (1) of the vehicles (2), the individual beam (1a) will be shielded (11a) everywhere except for one, which is the antenna itself (11) (see detail 2c, section A- A 'front of the beam), so that the electrostatic field generated inside the beam (1a) by the antenna (11) is oriented towards the open area, creating an electrostatic field (3) that allows detecting the disturbation in its region or zone of influence to notify the carrier soldier of the presence of any disturbance, which may be not only a mine, but also an FDI or even the presence of weapons buried in zulos or any other type of disturbance that can be characterized by the sensor (10) to which the antenna (11) of the individual beam (1a) is connected.
    IED detector and lapa pumps in vehicles
    In applications for the detection of FDI and barnacle bombs in vehicles, part of the embodiment for the detection of mines shown in figure 2a is increased and the number of disturbances (1) is increased, since for the detection of FDI and lapa pumps it is required a protection of the vehicle in 360 °.

    Ace! therefore, in a preferred embodiment, as shown in Figure 3, the vehicle (2) comprises a first antenna (11) that surrounds the vehicle perimeter and creates a first electrostatic field (3) next to the body of the vehicle itself vehicle, so that the closest threats can be detected and characterized, as an approximation of people or foreign objects attached to it.
    On the other hand, as in Figure 2a, the vehicle with the system configured for the detection of FDI will comprise, preferably a plurality of beams (1) of the same type as those indicated for the detection of mines but, given the special threat posed by FDI should generate an electrostatic field (3) also of 360 ° around the vehicle even in the upper zone, since many of these devices are located in urban areas in cornices and windows or in arboreal areas in the upper branches , so that the detection of these devices must be done with full coverage of the vehicle (2). Each of the antennas (11), preferably one per beam (1), will be connected to at least one sensor (10) located inside the vehicle (2).
    Preferably, the beams (1) will also form an angle (a) of 45 ° with the front of the vehicle (2) as in the case of Figure 2a so that the field can cover a greater coverage on the road and on the shoulders.
    Similarly, it should be remembered that the pertigas (1) of the embodiments shown in Figures 2a and 3 can not only have a variable angle (a) understanding this variable angle, so much so that they are in a fixed position at a certain angle that it can change as even that the disturbance (1) can be mobile to perform sweeps) but the length of it must be such that it allows a detection at a suitable safety distance, which can be, in a preferred realization 10 meters, but that it should never be less than the total length of the vehicle (2) and that it should preferably be at least twice the total length of the carrier vehicle.
    Weapons and explosives detector implemented in an individual weapon
    In addition to the individual disturbance (1a) of Figure 2b for the detection of mines or weapon areas, the same individual perturbation (1a) can be used to detect other types of threats, such as detecting the presence of hidden persons in buildings or hidden areas.
    In another embodiment, shown in Figure 4, the antenna (11) can be integrated into the soldier's own individual weapon, together with the sensor (10) connected with a control device (100) that warns the soldier of the threat and even set the friend / enemy identification, very
    important in this type of combat.
    Control Device (100)
    5 In all embodiments, all sensors (10) are connected to a control device (100) comprising: one or more processors (101); a memory (102); and one or more programs in which the program (s) are stored in the memory (102) and configured to be executed by at least the processor (101), including the programs instructions to: (i) characterize a detected disturbance by at least one sensor (10); (ii) 10 focus at least one camera (12) towards the zone of action of at least one sensor (10) with a detected disturbance; (iii) monitor the zone of action of a sensor (10) with a detected disturbance; (iv) generate a control signal and (v) communicate with a combat management system or BIMS (Battlefield Information Management System, literally battlefield management and information system).
    fifteen
    The control device (100) is the same in all embodiments and can be a specific electronic device integrated in the infantryman's combat equipment or be integrated in the control unit of a combat vehicle, or be any other electronic device as long as it complies with its own characteristics indicated for each realization.
    twenty
    In the different practical embodiments of the invention the control signal generated by the device (100) may vary. For example, the control signal is generally an alarm / warning that may also be associated with a friend / enemy identification signal through the combat management system or directly with an automatic weapon station to automatically perform a fire action, as long as the combat management system (which obviously includes the military command on the ground or the soldier himself) identifies the threat as hostile or allegedly hostile. Note that, in the realizations in the detection of FDI it is possible to destroy the FDI once it is automatically detected before it explodes and just after its identification, without giving time to the enemy's reaction.
