Abstract

PURPOSE:To detect only the desired Doppler signal accurately by a method wherein, after sampling a Doppler signal with a synchronizing pulse synchronized with a power source frequency, the sampling output is generated while the output is being maintained up to the next pulse. CONSTITUTION:An analog switch 30, a grounded capacitor C4, and a high impedance voltage follower 31 are connected to the rear level of a microwave Doppler signal sensor 20. Sampling the Doppler signal is carried out by ON and OFF controlling the analog switch 30 with a synchronizing pulse synchronized with a power source frequency from a pulse generator 32. This sampling output is held with the capacitor C4 to input the output to the high impedance voltage follower 31.
