RC vibrates, and oscillating circuit vibration produces high-frequency signal, amplifies through high-frequency triode, is emitted by the antenna on pcb board.
When receiving by human body, the isometric big object movement of automobile and the microwave reflection launched are returned frequency signal, interior
Beat detects faint frequency shift signal after the semiconductor PN mixing of portion's microwave high-frequency triode（Also Doppler effect is made to detect
The movable signal of human body）, the RC oscillating circuit plates outside triode Q2 high frequency pipe collectors launch 2.5-5.8GHz's or so
High-frequency microwave, receives the signal reflected by the loop aerial being distributed in outside the transmitting of PCB loop aerials, emitter stage, is sent out
Penetrate signal and carry out difference frequency, exported with 3-5HZ or so low frequency signal.The output signal is output to fortune by capacitance C14
