Abstract
In a CW radar system for detecting motion behind a wall () involving modulation of the radar transmission, means () are provided to interrupt the CW wave when motion is detected and to use the same radar transmitter () to transmit a serial digital message to a remote monitoring receiver (). The encoding can include a receiver wakeup message to turn on the receive only when motion has been detected. In one embodiment, a microprocessor () is used to detect when motion exists behind a wall and to provide a tailorable message to modulate the radar's transmitter in the period when the CW signal from the radar is turned off after the motion detector.
