Design and Implementation of 77G Radar System

Millimeter-wave radar sensors have the advantages of all-weather, all-day and other advantages. They have been used in aircraft and ship navigation from the early stage of research and development, and have gradually been widely used in automobiles. This paper designs a millimeter-wave radar system scheme based on the AWR1243+MUC+FPGA platform. Firstly, the external MUC is used to configure the parameters of each part of the AWR1243 chip through SPI to realize the startup of the chip. Then, through the realization of MIPI CSI-2 interface, the sampling data of radar intermediate frequency signal is extracted. Finally, according to the obtained radar data, the basic principle of frequency modulated continuous wave (FMCW) radar ranging, speed and angle measurement is studied, the radar target is detected by the two-dimensional constant false alarm algorithm, and the two-dimensional constant false alarm detection is detected by the method of point trace aggregation. The obtained radar target is reprocessed to obtain an accurate radar target.
