Title:
DOPPLER MICROWAVE DETECTION DEVICE AND DETECTION BOUNDARY ADAPTIVE ADJUSTMENT METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/088451
Kind Code:
A1
Abstract:
A Doppler microwave detection device and a detection boundary adaptive adjustment method therefor. The Doppler microwave detection device comprises an adjustment input unit (10), a feed circuit (30), a frequency mixing unit (40), and an antenna unit (100). The feed circuit (30) is electrically connected to the frequency mixing unit ( 40) and feeds and is connected to the antenna unit (100), to transmit an excitation signal to the frequency mixing unit (40) and to feed the antenna unit (100) by using the excitation signal. The adjustment input unit (10) is electrically connected to the feed circuit (30), and used as a human-computer interaction window of the Doppler microwave detection device. In the state of maintaining the independence of the operating frequency and impedance of the feed circuit (30), on the basis of the selection of corresponding input information of the adjustment input unit (10), the effective amplitude of the excitation signal is adjusted and the sensitivity of the Doppler microwave detection device is set.
