摘要
讨论了一种基于TMS320VC5402 DSP芯片的汽车防撞雷达系统,阐述了系统的工作原理、硬件结构和软件流程,该系统以毫米波雷达作为前端数据收发模块,定点DSP芯片为数据处理核心,采用混合语言编程及LMS算法,有效地提高了系统的运算速度与探测精度,及时准确地发现道路前方潜在的危险目标并进行报警。实验数据表明:该系统工作稳定可靠,可以有效降低交通事故发生率,满足汽车防撞雷达系统的实时性准确性要求。
This paper introduced the design method of the hardware and software for the automotive collision avoidance based on TMS320VC5402. It described the principle of the system in detail. Millimeter-wave radar received and transmitted the signal, DSP processed the digital signal. This system used two mixed programming languages and LMS algorithm, raising the speed of oper- ation and accuracy of detecting effectively. It is ready for the alarm when finding target. Experiments show the system is stable. It can lower the rate of accident, meeting the need of real-time and accuracy requirement of the system.
