76-81GHz frequency modulation wave FMCW radar product (also called millimeter wave radar), it uses a millimeter wave band with a higher frequency than Ku band radar, it can detect smaller targets and achieve more precise positioning than microwave radar with higher resolution and stronger confidentiality. Therefore, it has important applications in long-distance target detection, strong smoke and dust environment, long-distance imaging, multi-spectral imaging, etc.

What is millimeter wave electromagnetic wave: Usually the electromagnetic wave in the frequency domain of 30-300GHz (wavelength is 1-10 mm) is called millimeter wave. It is located in the overlapping wavelength range of microwave and far-infrared wave, so it has the characteristics of two kinds of wave spectrum.
