| 摘 要： | 基于发动机喷焰羽流对微波信号衰减的机理和等离子体的电子碰撞速度和电子数与温度的关系,根据喷焰羽流的红外图像,可以将喷焰羽流分成几层。通过透镜天线和对衰减多通道同时测试的方案,可以得到喷焰羽流衰减分布,并计算微波信号不同角度穿越喷焰时的衰减。

| Abstract: | As the mechanism of plasmas plume to the microwave attenuation,and the relation of electron collision rate and electron number to temperature,the plasmas plume can be delaminated according to infrared photos. Using lens antennas and multi-channel simultaneous testing method,the delamination of microwave attenuation crossing the plasmas plume can be found,and the attenuation crossing the plasmas plume from different angles can be estimated. |
