ABSTRACT:
A moving object detection apparatus in which an oscillating output, from a gate of an FET functioning as an oscillator, is coupled via a resonant line to a transmit-receive antenna, a wave, transmitted from the antenna and returned as a reflected wave, is received at the gate, and a beat signal component output from the gate, due to a phase difference between the transmitted wave and the reflected wave, is taken as a moving object detection signal.
