环形高功率微波脉冲压缩器的设计OA

[Background]In the fields of high-power microwaves and pulse compression,compared with exponentially decaying microwave pulses,the flat-top output has core advantages such as reducing the maximum transient surface field of the structure and enhancing system stability.Therefore,it has significant technical significance and application value.[Purpose]The purpose of this study is to develop a new method for power doubling that generates a flat-topped output and to observe its benefits through simulation experiments.[Methods]The research analyzes the energy storage process and the power gain and flat-top output width after input inversion based on the scattering matrix theory,and conducts simulation experiments using CST.[Results]The simulation experiment results show that its power gain is more than 5.7 times,the flat top width is 80 ns,the waveform is gentle,and the power capacity can reach 160 MW.[Conclusions]Compared with the existing technology,this design has a simple structure,compact volume and convenient processing and maintenance,providing a new solution for the stable output of high-power microwave energy and the research of two-stage pulse compression systems.
