请帮忙将下面论文摘要翻译成英文，谢谢！

本文论述了超声波测距的基本原理，测量、计算方法，并详细介绍基于超声波测距技术应用的倒车雷达系统的设计。该系统将微处理器技术与超声波的测距技术、传感器技术等相结合，可检测到汽车在倒车过程中，车后障碍物与汽车的距离，通过液晶显示屏显示障碍物距离、方位，并根据障碍物与车尾距离远近实时发出不同等级的警示声音。

Answer 1

This article elaborated the ultrasonic ranging basic principle, thesurvey, the computational method, and detailed introduction based onultrasonic ranging technology application back-draft radar systemdesign. This system the microprocessor technology and the ultrasonicwave range finder technology, the sensor technology and so on unifies,may examine the automobile in the back-draft process, after thevehicle the obstacle and the automobile distance, through the liquidcrystal display monitor demonstration obstacle distance, the position,and is away from the police according to the obstacle and thetailstock which far and near real-time sends out the different rank toshow the sound.

Answer 2

This paper discusses the basic principles of ultrasonic distance measurement, measurement, calculation method, and based on the detailed application of ultrasonic distance measurement reversing radar system design. The system will be the microprocessor technology and ultrasonic distance measurement technology, sensor technology, combining vehicle can be detected in the reverse process, the obstacles with the motor car the distance, through the LCD display barrier distance, direction, and in accordance with obstacles and rear distance issued immediately different grades the warning voices.
