Procedure for guiding a missile to a target upon loss of target

摘要

If a missile with a seeker loses a target, be it by exceeding a permissible maximum value of the squint angle or by loss of target radiation, for example with a passive radar seeker after switching off a radar position that is the target, the missile should still be guided to the target. This is achieved by storing the target loss position (14) and the line of sight DOLLAR I1 and guiding the missile (12) to the stored line of sight DOLLAR I2 starting from the stored target loss position (14). The missile is guided out of this line of sight by determining the current position DOLLAR I3 of the missile (12) relative to the target loss position, setting a virtual target (18) on the stored line of sight DOLLAR I4 in from the target loss position (14) a predetermined distance from the current position of the missile (12), calculating a virtual line of sight vector DOLLAR I5 from the missile (12) to the virtual target (18) and guiding the missile (12) in accordance with the virtual line of sight vector DOLLAR I6 .
