Abstract

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.

77G雷达系统的设计与实现

毫米波雷达传感器具有全天候、全天候等优点。它们从研发初期就应用于飞机和船舶导航，并逐渐广泛应用于汽车。本文设计了一种基于AWR1243+MUC+FPGA平台的毫米波雷达系统方案。首先，利用外接MUC通过SPI对AWR1243芯片各部分参数进行配置，实现芯片的启动。然后，通过MIPI CSI-2接口的实现，提取雷达中频信号的采样数据。最后，根据获得的雷达数据，研究了调频连续波(FMCW)雷达测距、测速和测角的基本原理，采用二维常数虚警算法检测雷达目标，采用点迹聚合方法检测二维常数虚警。对得到的雷达目标进行再处理，得到精确的雷达目标。
