摘要
速调管作为雷达发射机的核心部件,其性能的好坏直接影响雷达整机的性能;由于其腔体构造的稳定性和昂贵的价格等原因,使技术人员在检修中一般不怀疑其性能不佳而进入维修上的误区。通过对万州CINRAD/SB雷达故障报警信息进行跟踪,故障回顾,结合故障发生所伴随的工作环境与工作状态、测试数据,从发射机的工作原理出发,梳理了其功能模块,然后加以分析,探寻其发射机功率持续下降的原因,并加以总结,给出了雷达建设、维护维修中应当注意的一些问题、方法与建议。
As the core component of the radar transmitter, the klystron performance has a direct influence on the radar performance. But technicians are not willing to doubt Klystron＇s performance because of the structural stability of the cavity body and the high cost. As a result, the performance of Kiystron is usually not well judged. Some measures and suggestions to the problems generated in the process of constructing and troubleshooting of Radar are presented. Through tracking the fault alarm information of the Wanzhou CINRAD/SB radar, the faults generated are reviewed. In combination with the radar working environment and conditions when faults happened, the radar data are tested. By analyzing the function module based on the working principles of the transmitter, several reasons for the monotonously declining power of the radar transmitter are identified, and some countermeasures are given.
