一、前言由于713型气象雷达主要用于探测400公里范围内的暴雨、大范围降水及其他空间气象目标、警戒冰雹和台风等灾害天气,并可以在200公里范围内测定雨区的降水强度和强度的空间分布,以及测定降水云体的发展高度等,所以,该设备的正常运行对于本单位在保证飞行安全的气象信息服务中具有不可或缺的地位。本文对本单位在雷达使用过程中遇到的发射机脉冲调制器电路的故障,通过实际检修过程,介
I. Preface As the 713 weather radar is mainly used to detect heavy rainfall within 400 km, large-scale precipitation and other space weather targets, warning of hailstorms and typhoons and other disastrous weather, and can be measured within 200 km precipitation area rainfall intensity and The spatial distribution of intensity, and the determination of the height of the precipitation cloud body. Therefore, the normal operation of the equipment is indispensable for the unit in meteorological information services that ensure flight safety. In this paper, the unit encountered in the course of the radar transmitter pulse modulator circuit failure, through the actual maintenance process, mediated
