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.
