近距離マイクロ波センサ装置。 The antenna receives the reflected wave from the object to be measured of the radio waves radiated from the antenna fed by the frequency-modulated microwave oscillation source, and the received microwave signal is amplitude- or phase-modulated by the low-frequency signal. A mixer detects the modulated received microwave signal and the microwave signal obtained through the feeder to the microwave oscillation source, and the distance to the object to be measured is measured based on the detected signal value. A short-range microwave sensor device.
