<p>PURPOSE:To prevent the deterioration of misdistance by a method wherein a guidance signal, obtained by a seeker, is added sequentially with the stored data of a data memory unit to cancell the change of the changing rate of the angle of line of sight due to the acceleration and/or deceleration of a missile itself and effect homing flight of the missile on a straight line substantially toward an estimated point of rendez-vous. CONSTITUTION:An operating device 14 produces guidance correcting data at a plurality of times for correcting the amount of change of the changing rate of the angle of line of sight, which is generated due to the acceleration and/or deceleration of a missile, previously from a target information and the flight characteristic information of the missile while supposing that the flying target T does not effect acceleration, deceleration, turning and the like, then, stores them into a data memory unit 21 loaded on the missile. After the missile is launched and homing is started, a guidance signal, obtained by a seeker 22, is added with the stored data of the data memory unit 21 sequentially by an adder 27. According to this method, the change of the rate of change of the angle of line of sight due to the acceleration and/or deceleration of the missile itself is cancelled to effect the homing flight of the missile on a straight line substantially toward an estimated point of rendez-vous whereby the deterioration of misdistance is prevented.</p> |
