高功率微波大气击穿的光学诊断
-
摘要: 介绍了一种高功率微波在波导内击穿光电诊断测量装置，测得了大气击穿的光电信号，获得了HPM击穿形成的等离子体衰减常数，对击穿点向源方向移动的猜想进行了实验验证。同时进行了短脉冲HPM在自由空间击穿实验，获得了HPM在自由空间击穿的系统光学图像，分析了击穿的放电特征。Abstract: A diagnostic method of HPM breakdown in waveguide is presented. Experiment results, such as optics-electronics signal of air breakdown, the decline constant of HPM discharge plasma and verification of the conjecture that breakdown point shifts to source. In the mean time, experiment of short pulse HPM breakdown in free space is done. We take the systematic picture of HPM breakdown in free space. Therefore, the directly overall knowing to breakdown characteristic.
