STUDY OF GUIDANCE LAW FOR IMPULSE TERMINAL GUIDANCE SUB-MUNITIONS

In this paper, the guidance law for impulse terminal guidance sub-munitions is studied. It is used to attack immobile targets on the ground. In the line-of-sight coordinate system, the relation motion equation is given and the ignition line of impulse engines is put forward according to the concept of zero effort miss, and the correct thrust orientation is gotten. The computational results show that this guidance law can restrain turn rate of line-of-sight effectively and insure precision attack to the target.
