Description

 The present invention relates to the field of protection of units and subunits on a march under the influence of reconnaissance and strike complexes of the enemy, having as their means of destruction warheads equipped with combat elements with homing heads.

 Currently, devices for protecting objects of technology from homing weapons in the form of fortifications and armor structures are widely known. However, these devices protecting equipment against homing weapons do not provide complete protection for units and units on the march and hamper the maneuverability of equipment.

 Of the devices used to protect equipment from homing weapons described in the literature, the remote controlled ejection device for false targets [1] is close to the claimed invention. It contains two mechanisms for ejecting false targets (dipole reflectors and infrared traps) and a control unit.

 When protecting immovable objects from being hit by homing weapons, automatic devices for ejecting false targets are installed permanently in the area of each of the protected objects, and when protecting movable objects of equipment on each of the units (ship, plane, tank, etc.). The mechanisms for ejecting false targets are activated from the control unit of the machine after the personnel of the equipment have received a signal from the air defense warning posts (or from the control column of the column on the march with a radar station) about enemy air raids by means of communication means. The time from the receipt of the signal to the enemy air raid is in the tens of minutes, which allows timely protection of equipment. Moreover, infrared traps (false IR targets) thrown by the machine divert missiles with thermal homing heads, and dipole reflectors (dipoles) of missiles with homing radar heads, forming false targets. With a large number of ejected dipoles, a complete disruption of the automatic missile radar homing system aimed at the object is possible.

However, the well-known automatic ejection systems of false targets do not provide complete protection for the convoy of combat and special equipment on the march if the enemy uses reconnaissance-strike complexes (RUK) intended for reconnaissance and destruction in any weather conditions and at any time of the day, accumulations of equipment and marching units and formations of armored and mechanized troops, as well as other mobile equipment and comprising:
weapons reconnaissance and guidance aircraft;
ground mobile control center;
guided ballistic missiles of the ground-to-ground and air-to-ground classes with cluster warheads equipped with warheads with homing heads (infrared and radar).

 When an adversary uses an ARC, the probability of detecting missiles is sharply reduced due to their low effective reflective surface and significant flight speed, and the time required to use protective equipment (automatic devices to eject false targets) is also significantly reduced, since from the moment a target is detected to its defeat by reconnaissance and strike the complex runs only 2.4 minutes. This time is clearly not enough to detect the rocket to transmit information to the control points of the movement of the column of equipment, and from it to transmit a signal to the moving objects of the equipment and use machines on them.

 In the presence in the warhead directed by the HAND towards the convoy of warheads with homing heads of other promising types (laser and television), the known device will not at all provide protection for moving vehicles on the march.

Known counteraction system "Counter measures system" [2] which contains:
a) automatic devices for the ejection of false targets (launchers), while false targets include infrared traps and dipole reflectors (metallized tape);
b) scanning radar (radar);
c) RF receiver;
d) an indicator of the type IKO, providing an indication of the location of the target (enemy);
d) microwave transceiver (traveling wave lamp);
f) control and control center;
as well as other signs that reveal in more detail the control system for means of launching traps and hitting the enemy, means of exposure, through which the enemy can be deceived, etc.

 The Sybil system [3] is also known, which is an improvement of the above-described device, which, in addition to the above features, also contains a device for instantly placing an aerosol curtain of a screening curtain against guided missiles equipped with IR, television and laser seekers.

 However, both known devices [2] and [3] have a number of significant drawbacks. Known devices have a complex control system, which can lead to failure of the entire device, and, in addition, the dimensions of the protected unit of mobile equipment are not always possible to install these systems on the unit. They are intended to protect only the mobile unit on which they are installed. So, during the armed clash between Great Britain and Argentina, the Atlantic Conveyor container ship was destroyed as a result of the re-targeting of the UR AM-39 EXCET, launched on the Invincible aircraft carrier (according to other sources, on the Hermes aircraft carrier). The rocket under the simultaneous influence of active and passive interference turned to the right and captured the next major target, located near the aircraft carrier, a container ship. He was struck at the moment when a cloud of dipole reflectors was just forming and could not protect him.

 Achievable technical result increased survivability of equipment on the march in the conditions of the enemy using cluster warheads equipped with combat elements with homing heads, as well as simplifying the design of counteraction systems.

 To achieve this result, a radar sensor, a transceiver with an antenna-feeder device, and a trigger pulse are introduced into the device for protecting equipment from homing weapons, which contains an automatic ejection device for false targets and a device for instantly setting aerosol curtains. In this case, the transceiver is connected with a radar (RL) radiation sensor and a trigger pulse shaper, and a trigger pulse shaper, in turn, with an automatic ejection device for false targets and a device for instantly setting aerosol curtains.

Therefore, the signs of the proposed device protection equipment on the march are:
a) radar sensor;
b) a transceiver with an antenna-feeder device operating in the VHF band;
c) a trigger pulse shaper, for example a waiting multivibrator;
g) a device for instantly placing an aerosol curtain;
e) automatic ejection of false targets;
f) communication of the transceiver with the radar detector and the trigger pulse shaper;
g) the connection of the trigger pulse shaper with the automatic ejection of false targets and the device for instantly setting the aerosol curtain.

From a comparative analysis of the object of the invention with existing systems of counteraction, the hallmarks of the proposed device are:
a) radar sensor;
b) a transceiver with an antenna-feeder device operating in the VHF band.

 It should be noted that it has nothing to do with the microwave transceiver of the device [2] both in terms of objectives and the principle of operation. This VHF transceiver is associated with a radar detector and a trigger pulse shaper. When the RL-radiation sensor detects the fact of detection of the protected object of the radar seeker, the sensor generates a detection fact signal and transmits it to the VHF range transceiver, which emits it with an antenna-feeder device in order to notify other objects of the column, and also transfers it to the start pulse shaper ( this is the operating mode I of the device). In mode II, the VHF band transceiver receives the signal with an antenna-feeder device and also transmits it to the trigger pulse shaper. A microwave transceiver of a known device mounted in a superstructure of a ship transmits RF energy corresponding to the antenna-feeder device discretely in frequency and phase to that received from the adversary.

 Thus, the microwave transceiver operating in the mm range is designed for completely different purposes and does not correspond to the VHF range transceiver both by the principle of its operation and by the range of its operating frequencies.

 c) a trigger pulse shaper (for example, a waiting multivibrator), directly connected to the VHF range transceiver, an automatic machine for ejecting false targets, and an instant aerosol curtain device. (In the device [2] as in [3] there is a control and monitoring center. It consists of a console control panel, a data processing computer and information display means, a manual control unit and other system units).

 Thus, the proposed trigger pulse shaper is a simpler system that most fully meets the requirements for the equipment protection device on the march, in contrast to the control and monitoring center.

 d) the presence of connections of the transceiver with the radar detector and the trigger pulse shaper, as well as the connection of the trigger pulse shaper with the automatic ejection of false targets and the device for instantly setting the aerosol curtain.

 In FIG. 1 schematically shows a device for protecting equipment on the march from the effects of cluster warheads; in FIG. 2 is a diagram of the implementation of these devices to protect the entire column of equipment.

 The device for protecting equipment on the march from the effects of cluster warheads contains a radar sensor 1, a transceiver 2 with an antenna-feeder device 3, a start pulse shaper 4, an automatic ejection device 5 and an instant device for aerosol curtains 6. Moreover, the transceiver is associated with a radar sensor and a trigger pulse shaper, and the latter with an automatic ejection of false targets and a device for instantly setting aerosol curtains.

The device for protecting equipment on the march from the effects of cluster warheads is placed at each object of the equipment column. On the march, it works in two modes:
in the mode of fixing the fact of detecting the object by the radar homing head of the combat element of the enemy’s cluster warhead (mode I);
in the mode of receiving a warning signal from other objects that have detected a homing radar aimed at them (mode II).

 In mode I, the radar sensor 1 detects the fact of detecting a moving object, on which the device is installed, by a combat element of a cassette warhead of an enemy reconnaissance-strike complex by radar radiation from its homing head and generates a detection fact signal. This signal is transmitted to the transceiver 2 (for example, transceiver equipment of the VHF band). Then the signal of the fact of detection is emitted by the antenna-feeder device 3 in order to notify other moving objects of the column technology, and also enters the trigger pulse shaper 4, for example, a waiting multivibrator. The signal generated by the trigger pulse formation device enters the ejection machine of false targets, which triggers dipole reflectors and false IR targets (infrared traps) using this signal. In addition, the trigger signal is supplied to the device for instantly placing aerosol curtains 6, which provides masking of a moving object in the visible and infrared spectral regions by an aerosol cloud.

 In mode II, the operation of the device is similar to that described above except that the trigger signal is generated by device 4 (trigger pulse shaper) from an alert signal received from other objects of the column’s technology on the march through devices 2 and 3, respectively (if the non-radiating object is directed at the object homing head: infrared, television, laser).

 Thus, when a convoy of vehicles moves on a march if it is detected by an enemy reconnaissance-strike complex and uses cluster warheads consisting of combat elements with homing heads (see Fig. 2), a fact is recorded by the radar sensor of one or more protection devices the object is detected by the homing radar and a signal of the fact of detection is transmitted to the transceiver. Through the transceiver, this signal enters the start-up pulse shaper of the object protection device detected by the homing radar and to the transceivers of the protection devices of other objects of the column equipment and from them to the start-up pulse shaper. Then, from the triggering pulse formers, the triggering signal is sent to the ejection machines of false targets and devices for instantly setting aerosol curtains. In this case, the dipole reflectors 7, infrared traps 8 will be ejected and the aerosol cloud 9 will be placed over the entire column of equipment on the march.

 The use of this technical solution installed on all moving objects of the convoy’s equipment will allow reliable protection of all moving objects making a march from combat elements with various types of homing heads when a reconnaissance-strike complex of the enemy is detected by a column and its use of cluster warheads conventional ammunition of enemy aircraft, bombs, unguided rockets, having on its board a radar station. Thus, the use of the proposed device for protecting equipment on the march from the effects of cluster warheads will increase the survivability of the entire column of mobile equipment and will allow them to solve the combat tasks assigned to them in full.
