The modulation mode of the side slope monitoring radar in the patent adopts sawtooth wave modulation. When the FMCW radar is modulated by sawtooth waves or triangular waves, the frequency of a radar transmitting signal is linearly changed in a modulation period, and the FMCW radar adopting the modulation mode is a linear frequency modulation continuous wave LFMCW radar, and the distance information of a corner reflector is extracted according to the corresponding relation between the frequency difference and the time delay between transmitting signal echo signals. Compared with the radar of other systems, the LFMCW radar has the main advantages that a wider transmission signal frequency modulation band can be realized, and the high range resolution is realized; the period of the low modulation signal is much larger than the time delay of the target echo.
The corner reflector is a radar wave reflector with different specifications and made of metal plates according to different purposes. When the radar electromagnetic wave scans the corner reflector, the electromagnetic wave can be refracted and amplified on the metal corner to generate a strong echo signal, and the strong echo signal can prolong the working distance of the radar.
