1. In a side-looking airborne pulse radar system, means for maintaining the direction of an echo received in the middle of each recurrence from a ground area observed by the radar system, substantially coincident with a predetermined axis, comprising:

  • angular measuring means responsive to the angular interval between said axis and the direction of received ground echos and to the pulse repetition frequency of the radar system for providing an output signal indicative of the amplitude and the sense of the angular inerval between said axis and the direction of the echo received in the middle of each recurrence; and

    frequency controlled pulse repetition frequency generator means coupled to the output of said angular measuring means for controlling the pulse repetition frequency of said radar system so as to tend to reduce said angular interval to null.
