Abstract: In a monopulse radar system the phase difference between successive echoes from the same target is modified to make this difference equal to what it would be if the target were on the axis of the beam.

Abstract: In a moving side-looking coherent detection system, wherein the transmitted pulses are linearly frequency modulated, the echoes are submitted to a compression which is a function of the range of the target from which they originate, and by means of which the recording of the echoes on a photographic film displaced at a speed proportional to that of the system, supplies, for each echo, a pattern similar to that of a Newton ring; the observation of that pattern with a coherent and plane luminous wave and an appropriate conventional optical system allows the direct vision of the position of the target.
