A launch aircraft launches a bomb at a target and uses a radar to transmit a predefined waveform at the bomb and target. The bomb incorporates a transponder that frequency shifts the transmitted waveform and illuminates the target with a shifted waveform having a null at the center of its beam pattern. The initially transmitted waveform and frequency shifted waveform are reflected from the target and are received by the radar. The received signals are processed to generate a correction signal that is a function of the offset between the null of the frequency shifted waveform and the target location. The correction signal is transmitted to the bomb and is processed therein to correct the flight path of the bomb toward the target.
