A microwave detection device is provided based on Doppler effect principle, wherein by dynamically adjusting a frequency parameter of the microwave detection device, a frequency of an electromagnetic wave emitted by the microwave detection device is maintained dynamically to reduce a chance of one of odd-order harmonic frequencies, even-order harmonic frequencies, and doubling frequencies of the electromagnetic wave matching with the same frequency as the operating frequency of other radio devices, so as to reduce an interference of the microwave detection device with other radio devices. The frequency of the electromagnetic wave received by the microwave detection device is maintained dynamically to reduce a chance of the frequency of the electromagnetic wave matching with the same frequency as the operating frequency of other radio devices, so as to reduce an interference of the microwave detection device with other radio devices.
