Description

The described invention relates to methods for hitting group targets with cruise missiles.

A known method of hitting a remote ground target with the Tomahawk cruise missile BGM-109 (USA), in which they obtain information about the coordinates of the target from external sources, prepare the missile for launch, enter the flight mission into the onboard missile control system, launch the missile, at the launch and the flight marching sections carry out automatic missile control according to the on-board control system (BSU) commands using the on-board digital computer (BCM), inertial platform and bar altimeter, after The envelope envelope of the terrain to the BSU connects the navigation navigation equipment and the correlation subsystem for controlling the terrain contour TERCOM, using electronic terrain data and a radar or laser altimeter, as well as the DSMAC electronic-optical correlation subsystem using digital images of previously captured areas of the terrain on the route flight, perform automatic missile control in the area of breakthrough of the enemy air defense system (air defense) by commands B In using the embedded algorithms into it, suggest the missile at the target for teams BSU, hit the target and hit it [1 - Novikov AV Methods and control systems for modern missile weapons. - SPb .: VMI, 2002 .-- 75 p. S. 67].

For effective destruction of remote 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 this method of destruction as the inability to retarget a missile in flight, depending on the results of the target’s attack with the previous missile.

There is a method of hitting a group of ground targets 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 the telecontrol system transmits information to the control point at which data is received on the missile's hit or miss, then transfer the line of sight of the next missile to another target [2 - Patent for invention RU 2439462 C1. The way to control high-precision weapons / Golovan M.M. et al. - M .: FIPS, 2012. Bull. No. 1]. This method allows you to retarget the rocket depending on the result of the attack of the target of the previous rocket, but the retargeting range is limited by the telecontrol range, which is its drawback.

Known guidance systems for precision weapons that allow you to hit remote group targets. In contrast to the methods discussed above, in such systems they 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 by terrain using an air system target designation, recording in the rocket decoder before launching the electronic address, which is its “electronic key” for decrypting the transmitted information, etc. which only stands for "own" information and missile transponder responds only to "own" the request. Such guidance systems allow, on a site with combined control, to transmit the corrections of a flight mission to each missile and, if necessary, redirect it to another target [3 - Patent for invention RU 2596173 C1. High-precision weapon guidance system / Rakhov E.V. et al. - M: FIPS, 2016. Bull. No. 24], [4 - Patent for the invention RU 2284444 C2. The guidance system of high-precision weapons of the far zone / Shipunov A.G. et al. - M .: FIPS, 2004. Bull. No. 36]. These guidance systems allow you to hit remote group targets and redirect missiles in flight, depending on the results of their attacks with previous missiles, but only in the area with combined control, again limited by the range of the radio command telecontrol.

There is a method of hitting a remote group target with anti-ship cruise missiles "Granite" or "Yakhont", in which they obtain information about the coordinates of the target from external sources, prepare the missiles for launch, enter the mission into the missile launcher, assign the first leading salvo missile and launch the missiles , on the starting and marching phases of the flight, automatic missiles are controlled by their BSU commands using a digital computer, an inertial platform, an altimeter and a mutual information exchange system (VZOI), with where the leading missile’s functions can be transferred to another missile, after the first detection of the target by the homing radar of the first missile, they reduce the flight altitude of all “flocks” and take them beyond the radio horizon, automatically classify targets in the leading missile launcher, select the main target and they aim the estimated number of missiles at it, distribute the remaining targets between the remaining "flocks", in the missile control system of each missile, they automatically control the flight at the breakthrough section of the air defense system of the assigned missile ate using the algorithms laid down in the BSU, direct the missile at the target and hit it, after destroying 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 a group target, select the main one and effectively hit it with a "flock", retargeting the missiles during the attack.

The disadvantage of this method is the need to find all the salvo missiles within the radius of the VZOI.

The aim of the invention is to develop a method for hitting a remote group target, allowing to take into account the results of the target’s attack with the first missile, on the basis of which it is possible to adjust the flight route of the next missiles, retarget them and, if possible, inform their control point about the shooting results.

This goal is achieved due to the fact that a method is proposed for hitting a remote group target, in which they obtain information about the coordinates of the target from external sources of information, prepare missiles for launch, enter a flight mission into the on-board missile control system, launch missiles, and automatically control missile flight by their BSU teams using an on-board digital computer, an inertial platform, an altimeter and a mutual information exchange system (VZOI) at the starting and marching sections flight, in the flight section with the envelope of the terrain, connect the navigation navigation equipment and the correlation subsystem of the terrain contour with electronic data about it and the radar or laser altimeter, as well as the electron-optical correlation subsystem with digital images of the terrain that were previously captured on the flight path , control the missile according to the program for breaking through the enemy’s air defense line, direct the missile at the designated target and hit it.

Additionally, a radio link is established between two missiles fired at a time interval calculated on the basis of terrain folds, missile flight speed and a range that ensures stable radio communication between them, a common communication line is formed between all missiles of the pack, using radio links between pairs of missiles, encode and transmit "Along the chain" to the information behind the missile on the passage of the established sections of the route, the detected air defense systems, the beginning of the attack of the designated target, pointing at it and defeating it, gender The information obtained is processed in the BSU of each missile and, if necessary, the route is corrected, retargeted and reported “in a chain” to other missiles and the control point.

The invention consists in the following. The interval between missile launches, which provides reliable radio communication between two neighboring missiles, is calculated, and a radio link from the advanced missile to the last, right up to the control point, is formed “along the chain”. When preparing missiles for launch, they introduce a flight mission into each of them and assign targets. During the flight, the lead missile transmits to the missiles flying behind, information about the passage of sections of the route, the detected air defense systems and attacks of the intended target. Based on the current information received, each missile’s BSU carries out an analysis of the situation, if necessary, adjusts the route of movement and the coordinates of the target, after which they transfer the data “along the chain” to the next missile and control point.

The technical result of the invention is the ability to retarget missiles in flight depending on current information about the enemy, adjust the flight path of missiles, thereby increasing the probability of hitting targets, reduce missile consumption and promptly inform your control center about the results of firing.
