A guided missile is directed toward a ground level or sea level target despite the presence of laterally and vertically offset decoys by causing the missile first to “acquire”one of the target or decoys. The guidance system then directs the missile in the azimuth plane toward the acquired target while it directs the missile along a predetermined path that ends in a low level horizontal flight. A simulator simulates a flight path toward the acquired target in the elevational plane. When the simulated flight path toward the acquired target deviates from the predetermined elevational path by a preset amount, a logic system causes the missile to unlock from the target and acquire a new one. Thus the missile will ultimately only lock onto the sea level or ground level target.

A method of recognizing decoy targets serving to disguise a selected target and located at positions separated laterally and vertically from the selected target, using an active search head on a roll-stabilized missile homing on an acquired one of the targets along a flight path at a predetermined altitude, comprising producing a simulated elevation signal ahead of the missile in the elevation plane of the missile toward the acquired target; deriving from the predetermined altitude as increased by a constant value, an altitude signal, comparing the simulated elevation signal with the derived altitude signal; and, responsive to the simulated elevation signal exceeding the derived altitude signal, interrupting the homing guidance of the missile toward the hitherto acquired target, in the azimuth plane.
