PRESENTATION OF A DETAILED EXECUTION MODE OF THE INVENTION

[0021] An aim of the invention is a weapons and explosives detector that comprises different practical implementations, as shown below, each of the specific implementations of the parts that make up the weapons and explosives detector concerning the invention are listed.

[0022] The electrostatic field sensor (10) is a solution based on the sensor outlined in WO2015/044487 but improved for its use as a weapons and explosives detector.

[0023] However, in illustration 1, an alternative to this sensor is outlined. As can be appreciated in illustration 1, the electrostatic field sensor (10) comprises an antenna (11) that consists of one single electrode, which is, at the same time, transmitter and receiver (transmitter-receiver electrode) and is the antenna (11) used in each every one of the implementations that are put forth in this invention, albeit with different physical configurations and connectivities that can improve their functionality. It must be considered that several antennas can coexist in parallel in some implementations, albeit, each of them maintains the particularity of being a transmitter and receiver at the same time.

[0024] However, the controlled electrostatic field sensor (10) also involves a generation circuit and field measurement, preferably a tuner circuit with a work frequency of less than 5 MHz which comprises an RLC circuit and a phase stabilizer circuit. The signal received by the antenna, after measuring, goes through a filtration state and subsequently, this signal goes through a digital-analogue converter, which in turn is connected to a processor configured to detect the variations in the electrostatic field, creating a three-dimensional map with these variations, being able to define the volume and density of the object that has generated the variation. This processor, in turn, is connected to a radio frequency circuit that transmits an encrypted signal to a control device (100), which is external to the sensor itself (10) as can also be seen in illustration 5. The circuit is completed with a data storage memory.

Mine Detection

[0025] As can be seen in illustration 2, there are two potential devices for detecting mines, a vehicle configured for detecting mines (FIG. 2a) and a device for individual or manual use (FIG. 2b).

[0026] Experts in the field know that there are several types of land mines that are generally placed into two large groups: anti-tank mines and anti-personnel mines.

[0027] The anti-tank mines, in turn, are different in type depending on how they are activated, although the most common ones are magnetically activated, which respond due to the vehicle's proximity, and those that are activated through contact, either by touching them or by easing the pressure on the activation mechanism.

[0028] On the other hand, generally, the anti-personnel mines, activated through contact or pressure on them and their manufacturing materials vary considerably, with them preferably being plastic to avoid being detected, or metal, in the case of the older ones.

[0029] Therefore, the variety of threats means that the methods used to detect them must be flexible enough to detect any material in any position. So, the mine detection vehicle comprises an attachment at the front which houses at least one antenna (11) connected to at least one sensor (10).

[0030] In a favored implementation, shown in illustration 2a, this attachment at the front only consists of at least one pole (1) attached to the vehicle (2) in such a way that it can be retractable or telescopic, because it only needs to be unleashed in the event of combat, and not, for example, when the vehicle is the base or the barracks.

[0031] In the implementation in illustration 2a, the favored implementation is shown where the pole (1) forms an angle (a) at 45 with the front of the vehicle (2) given that, in this way, it's possible for the pathway of the roadside and its ditches to be controlled in one sweep. However, other solutions with the pole making other angles with the front of the vehicle could be considered depending on each use or specific application.

[0032] The antenna (11) will be housed inside the pole (1) in such a way that an electrostatic field (3) will be created around the pole (1) and directing the lower direction, using the shield of the upper part of the pole (1) (see illustration 2c, section A-A at the front of the pole). By doing so, the field is exclusively facing the ground, which the area where the anti-tank or anti-personnel mines are buried. In the same way, it can be seen in the illustration how there is also a perimeter antenna (11) which can create a second field (3) which is on the perimeter with regards the vehicle (2) itself.

[0033] In the same way, a manual device can be seen in illustration 2b for infantry use, which is essentially a pole (1a) made with light materials, for example, plastic or another non-conductive electronic polymer, and that can be equally extended for individual use. As with the pole (1) on the vehicles (2), the individual pole (1a) will be shielded (11a) on all sides bar one, which is the antenna itself (11) (see illustration 2c, section A-A front of the pole), in such a way that the electrostatic field created inside the pole (1a) by the antenna (11) is facing the open space, creating an electrostatic field (3) which can detect the disturbance in its region or area of influence to warn the soldier carrying it of the presence of a disturbance, which could not only be a mine, but also an IED, or even the presence of weapons buried in hideouts or any other type of disturbance that could be characterized by the sensor (10) that the antenna (11) is connected to from the individual pole (1a).

IED Detector and Car Bombs

[0034] In applications for detecting IED and car bombs, it is based on the implementation of mines shown in illustration 2a and the number of poles (1), because to detect IED and car bombs, a 360 protection of the vehicle is required.

[0035] Therefore, in a favored implementation, as shown in illustration 3, the vehicle (2) comprises a first antenna (11) that surrounds the vehicle and that creates a first electrostatic field (3) close to the vehicle's own bodywork, in such a way that the closest of threats can be detected and profiled, such as people approaching, or foreign objects attached to it.

[0036] On the other hand, like in illustration 2a, the vehicle with the system configured for detecting IED will compose, preferably multiple poles (1), the same type of those indicated for detecting mines, but which, given the special threat that IEDs pose, they must also generate an electric field (3) of 360 around the vehicle, even in the upper section, because many of these devices are located in urban areas on windows and ledges or even in areas with trees on branches high above. Therefore, detection of these devices must be done with full coverage of the vehicle (2). Each of the antennas (11), preferably one per pole (1), will be connected to at least one sensor (10) placed inside the vehicle (2).

[0037] Preferably, the poles (1) will also form a 45-degree angle () with the front of the vehicle (2) like the one in illustration 2a, so that it can cover the filed with better coverage on the pathway and the roadsides.

[0038] In the same way, it must be remembered that the poles (1) of the implementations shown in FIGS. 2a and 3 cannot only have a variable angle () (understanding this variable angle, both being in a fixed position at a specific angle and changing, as even the pole (1) can be mobile for sweeps) but also its length must be so to be able to detect at an appropriate security range, which could be, in a favored implementation of 10 meters, but it must never be under the total length of the vehicle (2) and which must preferably be at least double the total length of the vehicle carrying it.

Weapons and Explosives Detector Implemented on an Individual Weapon

[0039] Besides the individual pole (1a) in illustration 2b for detecting mines or hideouts with weapons, the same individual pole (1a) can be used to detect other types of threats, such as, detecting the presence of people that are hiding in buildings or in hidden places.

[0040] In another implementation, shown in FIG. 4, the antenna (11) can be included in the soldier's individual weapon itself, along with the sensor (10) connected to a control device (100) which will warn the soldier of the threat and even, identify the friend/enemy, which is very important in this type of combat.

Control Device (100)

[0041] For all the implementations, all the sensors (10) are connected to a control device (100) that comprises: one or more processors (101); a memory (102); and one or more programs where the program(s) are stored in the memory (102) and configured to be executed by, at least, the processor(s) (101), including the instruction programs for: (i) profiling a disturbance detected by at least one sensor (10); (ii) focusing at least one camera (12) on the at least one sensor's (10) operational area with a detected disturbance; (iii) monitoring the operational area with a sensor (10) with a detected disturbance; (iv) generating a control signal and (v) notifying a combat management system or BIMS (Battlefield Information Management System).

[0042] The control device (100) is the same for all implementations and it can be a specific electronic device included in the soldier's infantry combat equipment or even be installed in a combat vehicle's engine itself, or be any other electronic device, if it fulfils the individual features indicated for each implementation.

[0043] In the different practical implementations of the invention, the control signal generated by the device (100) can vary. For example, the control signal is generally an alarm/warning that can also be associated to a friend/enemy identification signal using the combat management system or directly, with an automatic weapons stations to automatically engage fire, if the combat management system (which obviously includes the force commander on the ground or the soldier himself) identifies the threat as hostile or presumably hostile. Consider that, in the IED detection implementations, the IED can be automatically destroyed on detection before it explodes and just after being identified, without giving the enemy any time to react.
