FIELD: weapons and ammunition.
SUBSTANCE: in using the method proportional navigation at the increasing drag trajectory part, the flight control can be started at a certain time. Also, velocity drop occurs at the moment of rendezvous because of inadequate distribution of control accelerations. The invention proposes using the time-variable navigation factor. The proposed method of guidance approximates, in fact, to the method of proportional navigation, but unlike it wherein the navigation factor makes a constant, the proposed method varies it depending upon known missile behavior at the drag trajectory part to maximise its velocity at the moment of rendezvous with the target.
EFFECT: decreasing the near impact zone, increasing the flight velocity at the point of rendezvous at the drag increase trajectory part.
