Pulsed a.m./f.m. c.w. radar

A novel radar system is proposed which effectively and simply combines the respective merits of pulsed a.m. and f.m. c.w. Doppler radar, by the use of a combined a.m. and f.m. waveform. Simple waveform changes permit the radar to be adapted to suit a wide range of operational requirements. This type of radar would require computer control for its full exploitation, and it is assumed that its principal application will be in fully automatic track-while-scan radars. The operation of the system in its various modes is described, and some technical aspects of the implementation of the system are discussed.
