摘要
根据GFE(L)1型二次测风雷达测角分系统的工作原理和故障诊断时应遵循的逻辑关系,将其功能电路归纳成相对独立的6个单元电路。按控制信号流程与单元电路的关系列出故障分析步骤,结合各单元电路关键点参数,能较快地定位故障元件。最后,列举了典型的故障实例,并介绍了维修方法和建议。
Base on the principle of angle measuring subsystem of L-band Secondary Wind-finding Radar and convenience for fault diagnosis,the functional circuits are sorted to six unit circuits.According to the relationship between the control signal process and unit circuits,the procedure of fault analysis is presented.Combined with the key point parameters of each unit circuit,the fault component can be quickly positioned.Finally,some fault examples are listed,and the corresponding repair methods and proposals are introduced.
