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
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).

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

waves of a certain frequency range in Hz, in a sector specific range, in a
direction A (25) and azimuth (22) to which the user wishes to search. 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.

Explosives detection system and
mixtures of average distances and depths
The invention relates to a, low cost portable system that detects in real
time, from a distance longer than 300 meters and to depths of up to 5 meters all known
explosive substances and mixtures provided timely to the operator of the
exact direction (azimuth) of explosive.

and international terrorism in the modern environment of international
terrorist groups designated and asymmetric threats.
