摘要
为了研究金属网反射面在空间中展开受到微振动是否对无源互调效应产生影响,在工程应用的基础上,设计了一种测试金属网反射面样件微振动下测试无源互调性能的方法,测试结果表明,不同张力的金属网样件在微振动下,无源互调结果浮动小于2 d B,试验数据为卫星工程应用提供了参考。
How the passive intermodulation (PIM) changes under micro-vibration when the reflector antenna is unfold in space is the research point. In this paper a method is designed for detection of PIM for metal mesh under micro-vibration. The test reslts showed the PIM result change is less than 2 dB. This provides a reliable reference for satellites engineering application.
