摘 要:本设计用AT89S51单片机为主控制器,设计一个汽车雷达系统,并且应用DSP作为辅助,实现了具有成本比较低、测距的精度高的调频连续波的雷达设计,同时还应用了电磁铁主动减速装置,起到防止碰撞的保护。应用毫米波作为雷达测量车距的工作方式,设计了一款功能多的雷达。本系统具有较强的适应性和广阔的应用空间,但还需要不断地改善与发展。40794 毕业论文关键词:51单片机;DSP;电磁减速;毫米波式的雷达
Automotive radar monitoring alarm system design
Abstract: This design use AT89S51 MCU based on controller design a car of radar system.And use DSP as auxiliary.To achieve the cost is too low.The design of the ranging precision and speed of FMCW Automotive radar Also use the electromagnet active deceleration device .To prevent collision protection To use the millimeter wave as radar system detecting .Design a more functional of automotive radar system. This system has strong adaptability and wide application space But also need continuous improvement and development.
