摘　　要：介绍了基于AT89C52单片机倒车雷达系统的设计方案,方案包括超声波测距电路、温度补偿电路、显示报警电路等硬件,还包含系统的软件设计,包括温度补偿程序、超声波发送和接收程序、语音报警程序等。测试结果表明,该系统是一款低成本、高精度、微型化LED显示的超声波测距倒车雷达。The hardware circuit design including an ultrasonic ranging circuit, temperature compensation circuit, display and alarm circuit and other circuits of the reversing radar system based on AT89C52 were ex- pounded. The software design of the system based on C language, the program of the temperature compensa- tion, ultrasonic send and receive, voice alarm were expounded. Results suggest that this is a low-cost, high- precision, miniaturized LED display, ultrasonic ranging reversing radar.
