Title:
MICROWAVE DETECTOR BASED ON DOPPLER EFFECT PRINCIPLE AND RADIATED INTERFERENCE RESISTANCE METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/191927
Kind Code:
A1
Abstract:
Provided are a microwave detector based on the Doppler effect principle and a radiated interference resistance method therefor. By means of dynamically adjusting a frequency parameter of a microwave detector, the frequency of an electromagnetic wave emitted by the microwave detector is kept dynamic, thereby reducing the probability of the electromagnetic radiation frequency of any of the electromagnetic wave emitted by the microwave detector, and odd and even harmonic frequencies and a frequency-doubling frequency of the electromagnetic wave being the same frequency as a working frequency of another radio device, that is, reducing the probability of the microwave detector interfering with another radio device. In addition, the frequency of an electromagnetic wave capable of being received by the microwave detector is kept dynamic, thereby reducing the probability of the frequency of the electromagnetic wave capable of being received by the microwave detector being continuously the same as the frequency of electromagnetic radiation at the same frequency band, that is, reducing the probability of other electromagnetic radiation at the same frequency band interfering with the microwave detector.
