The radar detection module 1 mainly comprises a high-frequency head, a pretreatment system, a terminal system, an infrared starter and the like, wherein a millimeter wave oscillator generates millimeter wave (8mm) oscillation, the frequency of the millimeter wave oscillator is set to be f0, the millimeter wave oscillation is added to a circulator through an isolator, the millimeter wave oscillation is radiated out in a directional mode through an antenna and is transmitted in a space in an electromagnetic wave mode, and when the electromagnetic wave meets a target (shot) in the space, the electromagnetic wave is reflected back. If the target is moving, the frequency of the reflected electromagnetic wave is added with a Doppler frequency fd proportional to the moving speed vr of the target, so that the frequency of a reverse echo becomes f0 +/-fd (the target takes "+" when approaching the flight and "%" when departing from the flight), the echo is received by an antenna, added to a mixer through a circulator and mixed with a signal (serving as a local oscillator signal) f0 leaked through the circulator in the mixer.
