基于DSP技术的汽车防撞雷达

Automotive Collision Avoidance Radar Based On DSP

简要介绍了各种汽车防撞技术的工作原理,分析比较了现有汽车防撞技术的优缺点,提出了一种基于DSP的可实现低成本、高精度测距测速功能的FMCW(调频连续波)防撞雷达设计方案,具体介绍了DSP在系统中的作用。

This paper introduces the principle of different automotive collision avoidance technology, analyses their advantage and disadvantage .And a design resolution of FMCW radar based on DSP is presented： low cost, high theoretical range and velocity precision. The operation of DSP is introduced in detail.
