| description | PROBLEM TO BE SOLVED: To provide a movement detection radar device wherein the electromagnetic wave of a microwave band being put to practical use for the purpose of detection of presence of a human life or guard at a disaster site is used without lowering the performance thereof due to a slight shock of the device itself. SOLUTION: The phase of a station transmitting high frequency signal 106 is modulated with a phase modulator by the use of the minute movement signal 105 of output of a tremor sensor 14 for detecting the tremor of an antenna and made a station transmitting high frequency signal 107. Thereby an unnecessary component included in a receiving high frequency signal 104 is eliminated, furthermore the unnecessary component due to the slight shock of the antenna 4 included in an output low frequency signal 109 is eliminated with a low frequency variable attenuator 13 and a low frequency adder 12 by the use of minute moving signal 105, and a low frequency signal 110 which includes only the movement of a moving electric wave reflection object 6 is obtained. |
