Description

The present invention relates to methods of hitting group targets with cruise missiles.

A known method of hitting a remote protected ground target with a Tomahawk BGM-109 cruise missile (USA), in which information about the coordinates of the target is received from external sources, the missile is prepared for launch, a flight task is introduced into the onboard missile control system, the missile is launched, the launch and cruise sections of the flight carry out automatic control of the rocket according to the commands of the on-board control system (BCS) using an on-board digital computer (BCVM), an inertial platform and a bar altimeter, after the start of the terrain enveloping, the navigation equipment of the binding and the correlation control subsystem along the contour of the relief are connected to the BSU terrain TERCOM, using electronic data on the terrain and a radar or laser altimeter, as well as an electro-optical correlation subsystem DSMAC, using digital images of pre-captured terrain areas along the flight path, perform automatic control e with a missile in the area of a breakthrough of the enemy's air defense (air defense) system according to the BSU commands using the algorithms embedded in it, aim the missile at the target according to the BSU commands, hit the target and hit it [1 - Novikov A.V. Methods and control systems for modern missile weapons. - SPb .: VMI, 2002 .-- 75 p. P. 67].

For effective destruction of protected ground targets, the number of missiles allocated to one target is increased, since some of them can be destroyed by air defense systems. This circumstance determines such a disadvantage of the specified method of destruction as the inability to re-target the missile in flight, depending on the results of the target attack by the previous missile.

There is a known method of hitting a group ground target with missiles, which differs from the one discussed above in that the first missile is launched in the direction of the nearest target, the target is captured by the missile guidance system and, via the telecontrol system, information is transmitted to the control point, where data on the missile hit or miss is received, after which the aiming line of the next missile is transferred to another target [2 - Patent for invention RU 2439462 C1. Method of controlling precision weapons / Golovan M.M. et al. - M .: FIPS, 2012. Bull. No. 1]. This method allows you to retarget the missile depending on the result of the attack of the target of the previous missile, but the retargeting range is limited by the telecontrol range, which is its disadvantage.

Known guidance systems for high-precision weapons that allow you to hit remote group protected targets. In contrast to the methods discussed above, such systems carry out combined missile control, including autonomous and radio command control, the subsequent transition to autonomous homing in the approach area to the target, search, recognition and determination of the coordinates of stationary targets located beyond the horizon or terrain folds using an air system target designation, recording in the missile decoder before its launch of the electronic address, which is its "electronic key" for decrypting the transmitted information, in which only "own" information is decoded, and the missile's radio responder only responds to "its" request. Such guidance systems make it possible, on a site with combined control, to transmit a flight mission update to each missile and, if necessary, redirect it to another target [3 - Invention Patent RU 2596173 C1. Guidance system for high-precision weapons / Rakhov E.V. et al. - M: FIPS, 2016. Byul. No. 24], [4 - Patent for invention RU 2284444 C2. Guidance system for high-precision weapons in the far zone / A.G. Shipunov. and others - M .: FIPS, 2004. Bull. No. 36]. These guidance systems allow you to hit remote group protected targets and re-target missiles in flight, depending on the results of their attack with previous missiles, but only in the area with combined control, again limited by the radio command telecontrol range.

A known method of hitting a remote group protected target with anti-ship cruise missiles "Granit" or "Yakhont", in which they receive information about the coordinates of the target from external sources, prepare the missiles for launch, enter a flight mission into the missile control unit, assign the first salvo rocket to the lead and launch missiles, at the launch and cruise sections of the flight, they perform automatic missile control according to the commands of their BSU using an on-board computer, an inertial platform, an altimeter and a system for mutual information exchange (IZOI), with the help of which the functions of the lead missile can be transferred to another missile, after the first detection of the target by the radar homing head (RGSN) of the first missile reduce the flight altitude of all missiles of the "flock" and take them beyond the radio horizon, automatically classify targets in the BSU of the leading missile, select the main target and aim at it the estimated number of missiles, the remaining targets are distributed among the remaining missiles of the "flock" , in the BSU of each missile make automatic flight control in the area of the breakthrough of the air defense system of the assigned target using the algorithms embedded in the BSU, direct the missile to the target and hit it, after the destruction of the main target, the remaining missiles are redirected using the VZOI system to other targets [5 - Novikov A.V. Methods and control systems for modern missile weapons. - SPb .: VMI, 2002 .-- 75 p. S. 60-62]. The method is based on the capabilities of the missile control system to automatically classify the group target, select the main target and effectively hit it with a "flock", redirecting the missiles during the attack. However, the disadvantage of this method is the impossibility of transferring information from one rocket to another at a great distance from each other, when the mutual exchange of information is technically impossible. So, the visibility range of the radio horizon, within which radio exchange between missiles can be carried out, is calculated by the formula:

where x is the range between missiles, km; yiiiyi- missile flight altitude, m; R is the radius of the Earth, equal to 6371 km. With a mid-flight altitude of two Tomahawk missiles equal to 60 m, the range of the radio horizon without taking into account the folds of the terrain will be 55 km [6 -Novikov A.V. Anti-submarine missile weapon. Theoretical basis. - SPb .: VMI, 2007 .-- 438 p. P. 178]. At a missile flight speed of 300 m / s, the launch interval between them for organizing radio exchange should not exceed 3 minutes, and taking into account the folds of the terrain, even less. Consequently, for effective destruction of remote group protected targets, taking into account the retargeting of missiles, the presence of one VZOI system between missiles is not enough; additional support is required for its operation at large distances of missiles from each other.

A known method of installing a repeater for organizing a radio communication link with an aircraft, in which on the flight route of the aircraft, a container with a repeater is dropped at a given point in space, the container is decelerated and divided into a repeater with a balloon compartment and a mooring device, a balloon is released, the mooring is pulled halyard, braking the mooring device and its attachment to the earth's surface, with the help of a balloon and a mooring cable, the repeater is held at a given height and at a given point in space on the earth's surface, the repeater is turned on or destroyed automatically or by an external signal [7 - Patent for the invention RU 2492574 C2. The method of installing a repeater when organizing a radio communication line / Petukhov V.P., Polyakov I.V., Rostopchin V.V., Starchenkov A.V. - M .: FIPS, 2013. Bull. No. 25]. The method is intended for organizing an independent radio link between a command post and an aircraft and can be used for organizing a radio link between two or more aircraft at a significant distance from each other or when flying in terrain folds.

The aim of the invention is to develop a method for hitting a remote group protected target, which will provide the ability to retarget missiles depending on the results of its attack by previously fired missiles and thereby increase the efficiency of the problem being solved.

This goal is achieved due to the fact that a method of hitting a remote group protected target is proposed, in which information about the coordinates of the target is received from external sources, prepare missiles for launch, enter a flight task into the on-board missile control system, launch missiles, and automatically control missile flight according to the commands of their BSU using an on-board computer, an inertial platform, an altimeter and a system of mutual information exchange (IZOI) at the starting and cruising sections of the flight before the beginning of the rounding of the terrain, in the section of the rounding of the terrain, the navigation equipment is connected to the BSU and the correlation control subsystem along the contour of the relief terrain, for which they use electronic data on the terrain and a radar or laser altimeter, as well as an electronic-optical correlation subsystem, in which digital images of previously captured terrain areas are used on the flight route, on the To break through the enemy's air defense (air defense) system, the BSU uses the control program developed for this, direct the missile to the target, hit it and hit the target.

Additionally, a radio communication line is organized between two or more missiles at a significant distance from each other or during flight in the folds of the terrain, for which a radio transceiver is installed on the missiles, an optical or infrared device is included in the missile guidance loop, and missiles are introduced into the BSU in preparation for launch alternate flight mission options and coordinates of other targets that are within the reach of the rocket, in flight at a given distance from the target or before the start of the breakthrough section of its air defense system, drop a container with a balloon or aerostat as a repeater from the rocket, transmit an image from the rocket to the repeater missile guidance systems and write it to the repeater's memory, encrypt and transmit it at the request of the VZOI system to the next missile or spacecraft, based on the information received from the repeater in the BSU of the next missile, assess the degree of hitting the target and make a decision to defeat it or retarget it on the track the target is transmitted through the spacecraft the recorded information to the control point.

The essence of the invention is as follows. When firing missiles at a remote group protected target at a significant distance from each other, a radio communication link between the missiles is organized by installing a repeater. The repeater, located on the rocket in a container and representing a balloon or aerostat, is dropped at a given point in space and attached to the earth's surface using a mooring halyard. An image from the guidance system is transmitted from the rocket to the repeater, recorded on a memory device and encrypted. At the request of the next rocket or spacecraft through the VZOI system, the recorded information is transmitted to the requesting rocket or spacecraft. On the rocket, in its BSU, the degree of hitting the target by the previous missile is assessed and a decision is made to re-engage or retarget it to the next target. The spacecraft transmits the information received from the repeater to the control center.

The technical result of the invention is to increase the likelihood of hitting each target in a group with a general reduction in missile consumption.
