Description

The invention relates to the field of control and regulation, and more specifically to guided weapons.

The invention is intended to control firing of a guided missile with a laser semi-active homing head from a launcher.

A known method of firing [Patent RU No. 2247297 of 02.27.2005, IPC 7 F41G 5/00, 7/22 - Method of firing a guided projectile with a laser semi-active homing head], which is as follows. The artillery battery is located at a long distance from the line of contact with the enemy. A scout is sent to the battle contact line with a laser rangefinder (LCD), satellite navigation equipment, a digital radio station and a reconnaissance console, and the LCD outputs, satellite navigation equipment and a digital radio station through connectors are connected to the reconnaissance console. The firing position commander has a commander’s console with satellite navigation equipment and a digital radio station. Using satellite navigation equipment, the coordinates of the LCD are determined and entered into the reconnaissance console. In the firing position commander’s console, satellite gun coordinates are entered from satellite navigation equipment, and meteorological and ballistic shooting conditions are entered from the keyboard. The scout, using LCD, measures the distance to the target, azimuth, and elevation angle of the target relative to the target indicator. The measurement results are transmitted to the reconnaissance console, converted into a rectangular coordinate system, displayed on the reconnaissance console’s screen and transmitted to the firing position commander’s console via a digital radio channel. The readings of the timer of the system time clock of the reconnaissance console and firing position are synchronized, for example, via a digital radio channel. In the firing position panel, using the radio coordinates of the targets, the measured coordinates of the guns, the meteorological and ballistic firing conditions entered, the firing settings for the gun and the projectile are calculated. The calculated installations are communicated to the gun commander, who directs the gun and prepares the shell. At the moment of a shot on the firing position console, the commander switches on the "Shot" button, and the time of the shot is read according to the readings of the timer of the clock system of the unified time of the firing position panel. A message about the fact of the shot and the time the LCD was turned on in the target illumination mode is transmitted via a digital radio channel from the firing position panel to the reconnaissance panel, where, when the necessary time is reached, a signal is sent to the LCD to turn on the laser radiation, by which the guided artillery shell is aimed at the target.

The disadvantage of the prototype is that for the timely inclusion of the laser radiation of the LCD, it is necessary to accurately record the moment of the shot, and it is necessary that the system time on the reconnaissance panel and the firing position panel is synchronized with high accuracy. In addition, a stable digital radio communication channel is needed between the firing position and the reconnaissance position, which can be difficult to ensure when positions are located at considerable distances or in conditions of very rough terrain.

The objective of the proposed invention is to increase the reliability of the complex by duplicating the generation of a command to turn on the laser radiation of the LCD on the radio signal emitted by the guided missile, which will eliminate the subjective human factor of fixing the instant of time of the shot and with a high probability to guarantee the inclusion of laser radiation of the LCD on the target at a given point in time .

This task is achieved due to the fact that in the known method of firing a guided missile with a laser semi-active homing head, including topographic reference of the target and the launcher to the terrain, target detection by the target, determining the coordinates of the target using the target and transferring them to the firing position console, calculation in the firing position console of the firing and flight missions of the guided missile, transferring the firing positions from the firing position console to the launcher and to guided cancer etu, firing a shot, installing a digital radio channel with a reconnaissance panel to transmit a signal through it to turn on the laser radiation of the target, automatic sending of a signal to turn on the laser radiation from the reconnaissance panel to the target, pointing the guided missile at a target illuminated by the laser radiation of the target, new is that together with the transfer of firing installations, the firing position console transmits to the guided missile the time for the laser radiation of the target indicator to turn on after the shot, digitally The first radio communication channel with the reconnaissance panel is set by a guided missile, and when the time for turning on the laser radiation comes, the guided missile automatically transmits a signal to turn on the target indicator laser radiation to the reconnaissance console.

Management of guided missile firing from the launcher according to the proposed method is as follows.

Using the navigation satellite equipment of the firing position console, the coordinates of the launcher are determined and stored in the memory of the firing position console. A scout has a reconnaissance console, to which a target indicator is connected. The scout, using the reconnaissance panel, determines the coordinates of the location, using the target indicator, detects the target and enters the polar coordinates of the target into the reconnaissance panel. Information about the target is transmitted over the radio channel to the firing position console. In the firing position console, target firing settings, launcher turning angles, the flight mission of the guided missile, and the time of turning on the laser radiation of the target after the shot are calculated. The calculated parameters are transmitted to the launcher and guided missile. A guided missile is launched. During the flight, the guided missile counts the time from the moment of the shot to the time when the target indicator laser radiation is turned on and, when this time arrives, the guided missile establishes a digital radio communication channel with the reconnaissance panel and automatically transmits the target indicator laser radiation activation signal to the reconnaissance panel.

To increase the reliability of operation of the designator, the signal for turning on the laser radiation of the designator is transmitted several times from the rocket through the digital radio channel, for example, up to 1-5 seconds.

This radio signal from a guided missile informs the reconnaissance console of the location of the guided missile in the target area and the reconnaissance console automatically transmits a command to turn on the laser radiation to the target, and the target automatically switches to target illumination by laser radiation, which guides the guided missile at the target.

To implement the described method, equipment can be used (reconnaissance remote control, firing position remote control, digital radio station, target designator) described in the patent [RU No. 2247297 dated 02.27.2005 IPC 7 F41G 5/00, 7/22 - Guided projectile firing method with laser semi-active homing head] and device [patent No. 2308070 dated 10.10.2007, IPC G05D 1/00 - Control panel]. The transmission from the guided missile to the reconnaissance remote control signal to turn on the laser radiation is carried out via a digital radio station of a similar prototype radio station.

Using the proposed invention will improve the reliability of the complex by generating a command to turn on the laser radiation of the target indicator on the radio signal emitted by the guided missile, which will eliminate the subjective human factor of fixing the instant of time of the shot and with a high probability to guarantee the inclusion of laser radiation of the LCD on the target at a given point in time.
