Research on High Power Microwave Radiation Electromagnetic Environment Simulation System

针对高功率微波辐射电磁环境模拟需求,研制了大功率微波辐射系统实验装置,该装置主要由脉冲调制器、脉冲磁控管、大功率馈线及辐射天线组成,介绍了各个组成部分的参数设计和系统辐射试验及测试结果。实验结果表明:辐射系统在辐射远场区的功率密度达到11.5 W/cm^2,能够满足开展相关高功率微波效应试验需求。

Aiming at the requirement of high power density electromagnetic environment construction, a high power microwave radiation system was developed. The system was composed of pulse modulator, pulse magnetron, high power coaxial waveguide and antenna. The design scheme of the system including fundamental composition and parameter design of each part is presented. Radiation experiments were carried out and the results demonstrated the system delivered a microwave pulse power density up to 11. 5 W/cm^2 at far field region, which can meet the requirements of high power microwave effect experiments.
