Abstract
A Doppler radar having a single sense Doppler signal from the rf mixer. A single sideband modulator in a common antenna system for transmitting and receiving shifts the fore and aft beams to achieve a single sense Doppler signal. The use of the single sideband modulator results in a differential Doppler shift between fore and aft beams of only a few hundred knots, thereby permitting use of low cost components. A single sense Doppler also reduces the Doppler passband by a 2:1 factor which permits the power supply frequency to operate at a higher frequency than the receiver.
