摘　　要：介绍了开式微波谐振腔测量系统的工作原理及试验结果,获得了φ10mm钢球模型在6.65kPa干燥空气中以速度5.44km.s-1飞行时的尾迹电子密度测量结果,并且与国外弹道靶试验数据进行了比较。试验结果表明,该系统能够满足模型尾迹电子密度变化对测量系统响应时间的要求,能很好地反映尾迹电子密度变化细节,电子密度测量范围达到109～1011cm-3。The principle and experimental results of the open microwave resonant cavity measuremensystem were introduced.The models were steel ball models and the ball models coated with copper.The diameteof the models was 10mm.The models were launched in ballistic range.The model velocity was 5.44 km·s-1.Thewake electron density of the models was obtained.The experimental results presents that the response time of thopen microwave resonant cavity measurement system was quicker than 1μs.The results showed the wake electrondensity ranged from 109cm-3 to 1011cm-3 could be achieved.
