摘要:

        提出一套含有盲区监测(BSD)与变道辅助(LCA)的24 GHz雷达系统,以便提醒驾驶员可 能出现的危险情况。定义了报警条件,设计了对雷达系统的波形,利用ADIsim PLL、SystemVue和 Matlab软件,对雷达的信号的生成及信号处理算法进行了仿真。设计和制作了由雷达壳体、信号处理 电路板、隔离信号处理电路板、雷达射频天线电路板等组成的雷达的硬件系统。对雷达系统的盲区监 测与变道辅助功能进行了实车测试实验。结果显示:雷达系统能够设定的危险工况下进行警告且不在 其他工况下进行警告。因此,本雷达系统开发符合相关的国际标准。

Abstract:

 A 24 GHz radar system with blind-spot-detection (BSD) and lane-change-assist-radar (LCA) was proposed to alert driver of possible dangerous situations. Under defined alarm conditions, designed a waveform of the radar system, and simulated the signal generation and signal processing algorithms of the radar by using the ADIsim PLL, SystemVue and Matlab software. Designed and fabricated a hardware system that was consisting of a radar housing, a signal processing circuit board, an isolated signal processing circuit board, and a radar RF antenna circuit board. A real vehicle test was carried out on the BSD and LCA function of the radar system. The test data showed that the radar system warns under dangerous conditions and does not warn under other conditions. Therefore, the developed radar system complies with relevant international standards.
