An X-Band Switched Energy Storage Microwave Pulse Compression System

An X-band switched energy storage (SES) microwave pulse compression system is presented, and its theoretical analysis, numerical simulation, and experimental research are carried out. Detailed dimensions of the resonant cavity are theoretically calculated and numerically optimized by simulation. The operation mode of the resonant cavity is TE1,0,52 at the frequency of 9.3 GHz. The output power gain is theoretically calculated as 11.7. When the width of the rectangular coupling iris is 11 mm, the coupling coefficient is 1.05, which is beneficial for high energy storage efficiency. In the preliminary experiments, the output microwave with power of 350 kW and pulsewidth of 10 ns is produced by the SES pulse compression system under the input power of 54 kW, implying a pulse power gain of 6.5.
