ABSTRACT:
The invention relates to missile-guidance systems of the semi-active homing type using the Doppler effect, designed for air-to-air, ground-to-air or ship-to-air installations. On the radar installation, a first illuminator comprising a directional antenna illuminates a target with a wave of first frequency F.sub.1. The wave reflected by the target is picked up by an antenna situated at the front of the missile. A second illuminator comprising a wide-beam antenna illuminates an antenna situated at the rear of the missile with a continuous wave of second frequency F.sub.2 coherent with the wave of frequency F.sub.1. The local oscillator in the receiver of the missile is phase-controlled in dependence upon the continuous wave of frequency F.sub.2.
