Abstract

A method and apparatus for synchronized clocking between a radar receiver and a radar transmitter includes sharing a reference signal between the transmitter and receiver, dividing the common reference into a transmit clock signal in the transmitter and a receive clock signal in the receiver. The receive clock signal and the transmit clock signal are synchronized using a trigger pulse. The synchronization is performed to achieve a 180 degree phase shift between the transmit and receive clocks. Radar pulse transmissions occur on an edge of the transmit clock coinciding with the trigger pulse. A signal recorder is activated on the edge of the receive clock each time the trigger pulse is received. The signal recorder is deactivated after a fixed interval based upon the receiver clock signal.
