摘　　要：雷达的种类繁多,用途各异。机载气象雷达的基本功用是探测航路上的雷暴雨、冰雹、湍流、风切变等恶劣气象区域。机载气象雷达(WXR)的安全性直接影响整机系统和飞行的安全。机载气象雷达是机载导航系统的重要组成部分,是民航客机上的一种重要导航设备。气象雷达出现故障极易造成飞机滑回、返航甚至坠毁等事故,因此必须加强对WXR的维护。本论文通过对机载气象雷达(WXR-700)基本工作原理的系统性总结,来全面地理解机载气象雷达相关知识,并对常见故障进行了总结、分析。There are many kinds of Radar, their uses are nut the same.The basic function of airborne weather radar is to deteet the route of thunderstorms, hail, wind shear, turbulence and other bad weather area.The safety of Airborne weather Radar （WXR） directly affects the whole aircraft system and flight safety.Airborne Weather Radar is an important part of the airborne navigation system is an important navigation equipment of civil airplane. If there is something wrong with Weather Radar, it may easily cause aircraft sliding back,return airport even crashes and other accident,so we must enhance the maintenance of WXR. This article summarizes the working primiple of WXR （WXR-700） briefly to undel^tand the related knowledge of WXR,and analysis,summarizes the common faults.
