Description

The invention relates to the field of weapons, military and special equipment (in particular - to missile and artillery weapons) and can be used in the development and creation of promising self-targeting combat elements (SPBE). The technical result is an increase in the probability of target detection, expansion of the combat use of SPBE, as well as ensuring the operation of the "shock core" from a height that provides guaranteed target armor penetration.

Known SPBE "Motiv-3M" [1], which includes an optoelectronic unit, a power supply and a unit for issuing control commands. The optoelectronic unit includes a passive infrared channel. The disadvantage of the SPBE "Motiv-3M" design is that the infrared channel is limited in use under unfavorable meteorological conditions (in conditions of fog, low clouds, etc.).

The closest in technical essence to the proposed invention is SPBE "SADARM" [2, 3, 4], which is taken as a prototype. It contains an optoelectronic unit, an electronic signal processing unit and a unit for issuing control commands. The optoelectronic unit is made in the form of a single unit, which includes passive infrared and active radar channels, the latter of which is simultaneously used as an altimeter.

A significant drawback of this SPBE is that in poor weather conditions it has low efficiency due to the low probability of target detection. This is due to the fact that in such conditions, only the so-called "cold" target, which does not have thermal contrast with respect to the underlying surface, will be recognized using the radar channel in the form of its outlines in overall dimensions. An infrared channel that recognizes a "hot" target, which could, in addition, determine the hottest area near the target and at the same time is the most vulnerable zone (engine compartment), will not work at all under these conditions.

It should be noted that the experience of conducting field tests of SPBE equipped with an infrared channel and an altitude sensor (altimeter) indicates that a number of SPBEs had heights of engagement of a warhead of the "shock core" type, exceeding the values established by the technical documentation, which does not guarantee required target armor penetration.

In addition, the experience of local conflicts in recent decades indicates that there is an objective need to identify the target "friend or foe" both during clashes with the use of armored vehicles on the battlefield, and during military operations in urban conditions, as well as guaranteed protection against accidental or unintentional impact by means of destruction of domestic production or "our own".

The purpose of the invention is to eliminate the above disadvantages of the prototype by introducing elements into its design that provide:

- increasing the probability of target detection - through the use of infrared, radar and radiometric channels and their integration;

- triggering of the "shock core" warhead from a height not exceeding the value established by the technical documentation, - due to the additional inclusion of two units: an altitude analyzer unit and unblocking and a radiation level analysis unit and target identification;

- expanding the capabilities of the combat use of weapons with SPBE - through the use of the "friend or foe" identification system.

The common features between the proposed design of the SPBE and the prototype are the presence of an optoelectronic unit, including passive infrared and active radar channels, an electronic signal processing unit and a device for issuing control commands.

Unlike the prototype, the proposed SPBE additionally introduces the following elements:

- passive radiometric channel;

- interrogator of the "friend or foe" identification system;

- block for height analysis and unblocking;

- unit for analyzing the level of emissions and target identification.

The essence of the invention is illustrated by a drawing, where FIG. 1 shows the general block diagram of SPBE.

The design of the invention includes a target coordinator 1, which consists of a passive optical two-spectral infrared channel 2, an active millimeter wavelength radar channel 3, a passive millimeter wavelength range radiometric channel 4 and an altimeter 5; interrogator of the "friend or foe" recognition system 6; a unit for analyzing the level of radiation (infrared, radar and radiometric signals) and identification (recognition) of the target 7, consisting of: a module for monitoring target identification by the interrogator of the "friend or foe" system (correct identification) 8, a module for monitoring the level of infrared radiation (correct detection) 9 , a module for monitoring the level of a radar signal (correct detection) 10, a module for monitoring the level of a radiometric signal (correct detection) 11, a module for monitoring the correctness of determining the height of the SPBE with an altimeter 12; an electronic signal processing unit (multisensor data processor) 13; block for height analyzer and unblocking (for issuing permission to generate a control signal (command)) 14; block for issuing a control signal (command) 15.

The proposed SPBE works as follows.

At a given point of the flight path of the weapon (missile, missile, air bomb, etc.), the warhead is separated (separated) and the SPBE is ejected. After a short-term unstabilized flight of the SPBE, the braking parachute is introduced and the altimeter 5, the radar channel (sensor) 3 and the “friend or foe” identification system begin to work. Then, upon reaching a certain altitude, the radiometric channel (sensor) 4 begins to function and after the command is given from the electronic signal processing unit (multisensor data processor) 13, the infrared channel (sensor) 2 is launched and the SPBE is put into a firing position. Signals from radar, radiometric and infrared channels (sensors) enter the control modules (correct detection, correct identification and altitude) 8-12, corresponding to each of them the unit for analyzing the level of radiation of infrared, radar and radiometric signals and identification (recognition) of the target 7 From unit 7, all signals are sent to an electronic signal processing unit (multisensor data processor) 13, in which, due to electronic processing, these signals are analyzed and compared with the threshold value of the level of radiation, signals. One of the main conditions for issuing a command (signal) to unit 14 (the height analyzer unit and unblocking for issuing permission to generate a control signal (command)) is the correct identification of the target by the interrogator of the “friend or foe” 6 system. Even if the threshold value is exceeded the level of infrared radiation and radar, radiometric signals on all channels in block 13, which will indicate the presence of a target, but the target will not be identified either as "our own", nor as "alien" or only "ours", then a signal (command) will pass to work on the self-destruction chain (U _{cp. on the SL} ) directly to the control signal (command) unit 15 and then from this unit a control signal is generated to detonate the SPBE warhead along the self-destruction chain. If there is correct target identification (after the target is identified as "alien"), the interrogator of the "friend or foe" identification system 6 and the threshold level of the radiation or signal value is exceeded by one of the detection channels (sensors) 2, 3, 4 of the target coordinator 1 this is the corresponding signal (command) to the altitude analyzer unit and unblocking to issue permission for the formation of a control signal (command) 14. In unit 14, after the signal (command) is received from the altimeter 5 that the SPBE is at the optimal height, which will ensure guaranteed armor penetration of the target, the blocking is removed and a signal is issued to generate a control signal (command) to work along the main circuit (U _{cp. on the OTs} ) to the control signal (command) issuing unit 15. Next, block 15 generates a control signal to detonate the SPBE warhead according to main chain.

The use of the proposed SPBE with an integrated aiming system and a "friend or foe" identification system will increase the probability of target detection, ensure its guaranteed armor penetration (subject to hitting the target), and also expand the possibilities of combat use of weapons with SPBE.
