Abstract: The present invention relates to a system for processing the signal received by a sideways looking airborne radar system. The received signals are compared with a sawtooth frequency modulated reference signal, the slope and the repetition period of which is a function of the velocity of the aircraft. The compared signals are passed through a digital integrator, the integration time of which is equal to the repetition period of the sawtooth. Control means, receiving the velocity of the aircraft controls the slope and the repetition period of the sawtooth and the integration time.
