| Abstract: | A brief introduction is made to the constituents and primary working principles of the CINRAD/CC radar solid-state modulator.According to data and the practical malfunctions of the Zhaotong Doppler radar,the causes of malfunctions are analyzed and handling methods are discussed.Through analyzing and summarizing,it is found out that common malfunctions of the solid-state modulator include mainly Silicon Controlled Rectifier(SCR),artificial line(PFN:Pulse Form Network) overvoltage,overcharging,SCR fan,and negative peak(value) faults,etc.The steady power supply system is specially important to the normal operation and service life of the solid-state modulator. |
