METHOD FOR FIRE BY GUIDED PROJECTILES WITH LASER SEMI-ACTIVE HOMING HEAD AT SEVERAL TARGETS Russian patent published in 2008 - IPC F41A1/00 F41G7/22 

FIELD: armament, in particular, control of artillery guided projectiles with a laser semi-active homing head locking-on the lighted target in the terminal trajectory leg and designed for fire control art a fire by guided ammunition with a homing head.

SUBSTANCE: the method consists in numbering of the guns, determination of the quantity and order of destruction of targets for each target beginning from the first one, measurement of the distance from the target indicator to the target, and of the target azimuth relative to the target indicator. Surveying of each target to the terrain in the reconnaissance console by computation according to the data o target indicator surveying, conversion of the co-ordinates of the targets in the reconnaissance console to a sequence of binary codes and transmission of them through the digital radio communication to the firing position console. Fire-mission setting for each gun is computed in the firing position console according to the co-ordinates of the respective targets and surveying of the respective gun at a computer time common with the reconnaissance console, realization of the fire-mission setting on the gun with the respective number. The shots are accomplished in the order of gun numbering, the command for fire by the next gun is produced by the firing position console according to the following relationship: Т_{fire i+1}=Т_{shot i}+ΔТ_{flight i}+ΔT_H-Т_{d.lm. i+1}, i=1, 2, ...n, where: T_{fire i+1}-time of output of fire command at the next target: Т_{shot i} - the instant of shot time at the i-th target; ΔТ_{flight i}-the projectile light time to the i-th target; ΔТ_H-the of target indicator reaming to the next target; ΔТ_{d.lm. i+1}-the delay of engagement of target indicator to lighting mode at the i+1-th target; n-the quantity of destructed target. Each shot is fixed in the firing position console, the target indicator after aiming of the projectile on the previous target is transferred to the next rated, and laser emission on each is engaged and disengaged by a signal from the reconnaissance console at attainment of the respective time preset the firing position console.

EFFECT: reduced time of destruction of several targets due to a complex delivery of fire by several guns at a number of targets with employment of one target indicator.
