Abstract: A radar system for continuously displaying target returns on a conventional television receiver. The radar includes a console connected to a rotating scanner unit through conventional slip rings. The scanner unit contains a radar antenna coupled to a receiver and transmitter, and a power supply generating a multitude of high-voltage and circuit supply voltages from AC power. A position transducer measures the rotary position of the scanner unit and triggers the transmitter as the scanner unit rotates. The return signal is thresholded to generate a video data signal, portions of which are sequentially stored in separate memory locations, each corresponding to a respective range. The set of video data in memory thus corresponds to targets within a predetermined range in a single direction.
