| Abstract: | 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. |
