Problems solved by technology

Based on the above-mentioned characteristics of millimeter waves, millimeter waves are widely used in the fields of communication, radar, remote sensing, and radio astronomy. At present, there are some human body posture recognition technologies using millimeter waves on the market, but the recognition process of existing technologies is relatively complicated. , the interference signal and noise signal in the millimeter wave signal cannot be effectively eliminated, and the obstacle cannot be accurately identified, eliminated or bypassed, the recognition result obtained is not accurate enough, and the reference value is not great
Moreover, the existing camera technology is prone to leak user privacy risks

Description

technical field [0001] The invention relates to the technical field of millimeter wave identification and monitoring, in particular to a human body intelligent monitoring method and monitoring equipment based on millimeter waves. Background technique [0002] Millimeter waves refer to electromagnetic waves with a wavelength of 1 to 10 millimeters. It is located in the wavelength range where microwaves and far-infrared waves overlap, so it has the characteristics of both spectrums. Compared with light waves, millimeter waves are less affected by natural light and thermal radiation sources; they have extremely wide bandwidths, and the frequency range of millimeter waves is 30GHz-300GHz, with the characteristics of high precision and high resolution; millimeter waves have narrow beams, in the same Under the antenna size, the millimeter wave beam is much narrower than the microwave beam, which can distinguish small targets that are closer together or observe the details of the t...
