| 摘 要： | 离子推力器工作时产生的等离子体羽流会对穿过其间的电磁波产生影响。为了解通信微波在羽流中的传输特性，在带有透波真空舱的专用设备上进行了羽流对微波通信影响的试验。采用的方法是将一对发射和接收双脊喇叭天线口紧贴透波舱两侧并正对放置来测试穿过羽流的通信微波的变化情况。试验结果表明:在1～5 GHz微波通信频段范围内，离子推力器所产生的羽流对电磁波的波幅和相位影响较小，幅度衰减不超过4 dB，相位偏差不超过80°。

| Abstract: | The exhaust plasma plume from the ion thruster would affect the electromagnetic wave that passes through it.To reveal the effect of 20 cm ion thruster＇s plume on the transmission of the microwave,tests were carried out in a special facility with a wave-transmitting vacuum tank.The test approach is to locate a pair of receiving and emission horn antennas at two ends of the tank over against to detect the microwave passing through the plasma plume.The results indicate that the amplitude attenuation is less than 4 dB and the phase shift is not more than 80° in the 1.0～5.0 GHz microwave band. |
