Abstract
A Doppler radar employing a common antenna for transmitting and receiving. A single sideband modulator (SSBM) is employed in the transmitting circuit to offset the rf reference frequency during transmit time and to discontinue offset during receiver ON time. Through a coupler and isolators an attenuated portion of the rf reference signal is applied to the receiver mixer at gated intervals. The output of the mixer are signals which are free of undesired reflected transmitter signals.
