Explosives detection system and mixtures

of average distances and depths

 

 

 

The invention relates to a portable system built into one device, relatively low operating costs, real-time scans of large and middle distance passing stationary or transportable explosive devices containing any known explosive substances and mixtures. The system provides timely the operator of the exact direction (azimuth) of the target.
In the most complex and advanced version activates automatically using various mechanisms microelectronics and sensors (sensors) to allow time for response to security personnel and safely evacuated the area, while not perceived by the terrorists. In the third and most advanced version interconnect multiple sensors - devices that detect all known explosives, sending real-time information about the type of explosive and the distance from the sensor to modern automated relays interfaced with sensors that operate in real time (C4ISR).
 In today's environment, the continuous evolution of the martial arts and sciences and shaped geostrategic policy combined with referred to as asymmetric threats of states harboring terrorism or individual forces or terrorist groups at national and international level, have created the need for rapid and effective treatment of functional and operational needs in research and technology.
 Moreover, from the fact alone that the explosives are and will remain a cheap, handy, easily constructible and important weapon especially regarding the psychological factors and their effect on the morale of the enemy, particularly on the civilian population, it is estimated that the development of this system to detect explosives, may be the first and key step responses at national and international level.
 The problem solved by the invention is the effective coverage of the need successful identification of large and medium distances, all explosives and mixtures of common strong explosive trinitrotoluene (TNT), plastic explosives C3 and C4, dynamite until the explosive ammonium compounds (ammonium nitrate, etc.). Approached significant objective'' effective protection of citizens - vital areas'' within the rapidly modulated global scene today geopolitical and economic upheaval.
The system is developed in two forms, one portable and one suitable for installation in places where it is estimated that it is possible to cross people illegally transporting explosives is relatively inexpensive, easy to use, easily constructible, autonomous in terms of energy and is estimated to be an important weapon in the fight against international terrorism in the modern ever-changing international environment, where most alarming increases the occurrence of asymmetric threats in space, time, quantity, quality, and in particular ingenuity of terrorists.

The particularity of the invention is that it detects explosive charge into the soil to a depth of 4 or 5 meters off ground beams longer than 300 meters having applicability in sensitive areas (airports, large ships, exhibition centers, malls, railway stations, Border control posts, government buildings, military establishments, VIP buildings, vehicles, etc.) without the localized terrorist perceiving the recognition of the illegal cargo, resulting in easier handling of the situation. The problem can be solved by applying compulsory passage (Figs. 5 and 6) passengers for example, an airport, by appropriate mazes (corridors without windows in closed circular or other irregular shapes) and trapping them in a special particularly shielded space where only reach will automatically close the doors back (Figure 7) and in front of them when identified over the explosive. Even if illegally bearing explosives detonate the explosives will be little to no casualties, always depending on the shield of the latter part of the runway should be from strong steel or special reinforced concrete. The case certainly requires entering one to one controlled by the maze.
This invention is an authoritative and scientifically proven solution, applying modern technologies. The whole idea is shown in Figure 1 and is based on the properties of electromagnetic radiation (26) partially reflected when they encounter some form of matter (18), carrying both the 'producer', ie the emitter, information about the texture of the material from which partially reflected after filtration.
Experimenting in the field has been observed that the explosive components with which experimented specific measurable return frequencies if they agree this show from the used generator frequency. It was found that the partially reflected spectrum of the components of the particular explosive material is not different from that produced by the subsystem generator frequency and transmitted by the twin antennas subsystem wide beam scanning.
From the spectral analysis of the returned signal was also the possibility of precise and specific to detect explosives, even when they are placed close to other objects with similar properties to those.
The system consists of a portable device (1) which comprises a number of design operated independent subsystems. These are the subsystem frequency generator (31) which produces a specific frequency and wavelength signals. The subsystem of twins extreme metal antenna broad beam scanning (33) transmits these signals to sector specific range. The subsystem identification or control (32) compares the returned signal frequencies with those observed attributed to the particular explosive (TNT, C3, C4 dynamite, etc.). The subsystem aid of reflected signals (35) directs the subsystem of metal medium narrow antenna beam scanning (34) in the direction that is the explosive substance. Finally, the power subsystem (36) provides the necessary electrical power for operation. Finally there is the subsystem output (37) of system (loudspeaker, headset, scale display function of the device).
  The operating principle of the system based on the existence and knowledge of the behavior of experiments measured for each explosive low frequency harmonics that the returned signal reveals the spectrum. The
intensity and the overall behavior of the harmonic frequency of the returned signals observed in practice that leads us to accurately detect specific explosives.

Low frequency signals generated by the subsystem generator output frequency (19) which is nested within a suitable metal casing (1) and broadcast to a selected direction of the operator (25) of the subsystem of the double end metal antennas (14) and (16 ) wide beam scanning called guides electromagnetic waves. The antennae are actually a type of 'V' straightener electromagnetic waves, which is coordinated with the central antenna transmission and reception of electromagnetic waves. All three antennas emit electromagnetic waves.
The low frequency signals when encounter any material surface (18) which can not penetrate partially reflected and collected by said subsystem twins antenna (14) and (16) a broad beam scanning. Then passed to suitably designed microelectronic circuit (32) disposed within the metal housing (1). This is the subsystem identifier and is responsible for identifying the signal in the system from the outside world, ie on reflectance signal was produced by the generator frequency emitted from the twin side antennas wide beam scanning. This circuit analyzes exactly the electromagnetic spectrum of the returned reflection wavelength on comparing the respective known spectrum measured in advance to the particular research explosive material and locks the frequency and direction, rejecting all other interference.
When comparing the data obtained advance knowledge of the harmonics that carry a reflected by the explosive signal, another microelectronic circuit located inside the metal casing (1), called electronic subsystem Micro engineering aid (35) working as micrometer amp drives the median antenna (15) to the direction or azimuth (22) where the returned reflected electromagnetic waves.
As the pilot nears scanning in a particular direction with the manual system (13) in ever closer to the explosive material to research, the more the microelectronic circuit that acts like micrometer amplifier returnable reflected electromagnetic signals, stabilizes the direction of the middle antenna to the target - explosive. The process is repeated continuously until this distance becomes too small, the system operator can now perceive the existence of explosive (18) with his own senses (visual).
  The high energy potential of the system - detector is determined by the relative sensitivity and intensity frequency generator achieves the efficient detection of all known explosives even in the construction of buildings, which include the back of the reinforced walls or wrapped with insulating material any .
The system - device provides high relation with respect to the capacity speed in relation to that obtained scanning. The narrow antenna beam scanning allows accurate identification of detected targets. By using appropriate electronic filters in the microelectronic circuit identification detector achieve differentiation between real parts explosives and any false "objectives (if any devices misled).

The development of the system aims at:
-Upgrading the entire system locating explosive devices with an estimated effect of strengthening the system for early warning of terrorist organization, or an organization or country will want to integrate it into the system.

Ability to detect all known explosive fillings containing the known common explosives in real time from the middle and long distances and on medium depths.
No need to use some other system to confirm the existence of explosives.
The casing which encloses the microelectronic system and sensors are suitable made both to provide maximum protection from external environmental conditions and to not cause interference, and generally malfunctioning sensors.
  Given the flexible structure so that both can be setting after continuous testing in the fields of exercise and secondly the possibility of acquiring knowledge for further technological evolution over time.
 Not alter the explosive charge to use the device. Not activated explosive devices from using the system.
 The sensitivity of the system may be predetermined according to the requirements of the end user.

There is capacity for two and more devices in positions so as to cover the entire spectrum of known explosive fills.

During field trials there was no interference of the system from another same or similar system.
The account system is not designed to identify components, self-supporting, firing mechanisms (caps, metal parts, components, soldering electronic devices, etc.) or other electronic devices containing semiconductor components (diodes, transistors, computer chips, etc.) or are used embedded to activate explosive fillings or for other purposes such as surveillance (microphones, amplifiers, microphones, tape and digital recorders, remote controlled devices, etc.)
The account system allows to control the structure of fabrics, furniture, wall, floor, etc., and the detection of explosives that may be hidden behind or within it including the case where the explosive is body.

The invention is described below with reference to the accompanying drawings in which:
Figure 1 shows the front of the portable - system explosives detection which is substantially encapsulated in a metal shell (1) that contains all the other subsystems of the three antennae (33) and (34). The last two are distinguished as a subsystem (34) middle-metal antenna (15) emission - reception and narrow beam scanning subsystem and (33) twins (14) and (16) extreme metal antenna broad beam scanning. All metal antennas are firmly connected (17) to a plastic shaft, called 'rotating axis detection'. (13) and can be adjusted by the energy of the operator in any angle he wishes only to the horizontal plane. The connection point (17) is not constant but allows the three antennas to move independently of the will of the operator in the horizontal plane, as the azimuth of the reflected electromagnetic wave explosive.

Connection point is cut filter and cosmic radiation, ie radiation from the environment in general or reflected on earth and are not desirable in our system. It also appears bipolar  cable (12) which connects the antennas to the main shell encapsulation (1) of the device - system. Then distinguished (3) mechanical selector cadence length and depth detection. Immediately right of distinguish the male connector (5) carrying three contacts in which the leads connected cord of the three antennas. The plug is encapsulated type female connector (4) to accommodate cables of the three antennas. Above this is the plug (11) a mechanical knob that adjusts micrometric subscale. Just up and left him there (2) the manual selection of the desired frequency detecting explosive (positions are similar to those for detecting explosives).

The explosive detection to (18) exists in another direction from this research (25). The transmitted signals (19) from the twin antennas will eventually meet the explosive (18). Then, in Figure 3, part of the above signals will be reflected (20) on the explosive (18), will change the direction (26) and move the antenna subsystem (14) and (16) of the device (1). The azimuth of the central antenna remains (23) as in the original direction of Figure 2. Once the returned signals (20) of the explosive (18) enter the subsystem identification and edited, enhanced and adequate support from the subsystem, a new electromagnetic wave (21) will begin to broadcast with the new azimuth (24) which is the explosive, and a system of antennas automatically without user intervention directed (28) on the horizontal axis and moves in the direction (27) of explosive. The central antenna (15) is led to a new location (29) line in the direction of the explosive and dragging the twin antennas (14) and (16) to move according to new positions (28) and (30), not aligned with the direction of the explosive, but keeping constant both the angle between them that the user initially appointed as but keeping constant the corners and the central antenna.
