ABSTRACT:
The invention provides a side-looking radar for use on a moving carrier and for exploring space laterally with respect to the displacement direction of the carrier. The receiver includes a non-coherent detector having a reference signal input. The average differential phase between the phases of successive received echo pulses appearing at the output of the detector is evaluated and utilised to control a phase shifting arrangement so as to bring the phases of the successive received echo pulses into alignment and establish coherence between the detector and the radar transmitter.
