Abstract
Back-draft radar is the safety and assistant devices when parking or reversing a vehicle, it can tell drivers circs about the around barrier with voice or a more intuitive display, release the surrounded visit puzzle from drivers when parking, reversing and start vehicles, and to help drivers clean off dead ends and the limitation of vision blur, improve the security of driving. It is used that single-chip tehnology ultrasonicranging and sensor technology in the system. . Using Single Chip AT89C51 of ATMEL and Ultrasonic Sensor measure distance to achieve Ultrasonic Back-draft Radar.
Key Words：MCU measuring distance ultrasonic sensor back-draft radar
