This paper is a survey of trends in the post-war development of continuous-wave and frequency-modulated radar with emphasis on systems designed to operate to short range. The larger part of the material is concerned with systems which use a single microwave generator as both a transmitting tube and as a source of local oscillator power. The discussion is organized around the various methods of analysis which may be used to study these systems. Hitherto unpublished work on a statistical method, developed at the Diamond Ordnance Fuze Laboratories, is summarized. Some information of a practical nature on microphonism, nonlinearities, feedthru, and saturation is included. A bibliography of work done in the post-war period is also included.
