METHOD FOR FIRE OF GUIDED MISSILE WITH LASER SEMI-ACTIVE HOMING HEAD (MODIFICATIONS) Russian patent published in 2007 - IPC F41G5/00 F41G7/22 

FIELD: armament, in particular, control of artillery guided missiles with a laser semi-active homing head, locking an illuminated target in the terminal trajectory leg, applicable for control of fire of mortars and cannon artillery.

SUBSTANCE: the method consists in topographical survey of the target indicator and firing position to the terrain, target detection by the target indicator, measurement of the distance from the target indicator to the target, azimuth and angle of sight relative to the target indicator under the conditions of successive target location. Topographical co-ordinates, direction and speed of target motion are calculated in the reconnaissance panel, the co-ordinates, speed and direction of target motion are transformed to a series of binary codes and transmitted to the firing position panel by the digital radio communication. On the basis of the obtained data and preliminarily preset meteorological data, ballistic corrections, time of preparation of the gun and missile to fire the predicted point of impact of the missile with the target an the ground surface is calculated, the fire settings according to the co-ordinates of the gun and the co-ordinates of the predicted point of impact of the missile with the target are calculated, the time of the shot for target destruction in the predicted point is calculated, the sole computing time is set in the reconnaissance panel and in the firing position panel, the fire settings are realized. The signal for a shot is given from the firing position panel when the time of the shot is coming. The time of switching-an of the target indicator of laser radiation is transmitted from the firing position panel to the reconnaissance panel via the digital radio communication channel. The signal for switching-on of the laser radiation target indicator is automatically given from the reconnaissance panel when the required time of switching-on is attained, and the missile is guided to the target illuminated by the laser radiation of the target indicator.

EFFECT: enhanced accuracy of fire at movable targets.
