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.
