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.
