一种航天器射频设备频谱兼容性分析方法

摘要

Aiming at the shortage of the traditional electoral-magnetic compatibility（EMC） design for spacecrafts,the principle of frequency spectrum compatibility analysis method on RF equipments in spacecraft is presented.The analysis method is applied for spacecraft,and the factual engineering cases verify its validity.The process of forecast and analysis on RF equipments and corresponding points for attention including the margin of electromagnetic interference are provided.%针对传统航天器系统级电磁兼容性设计的不足,阐述了航天器射频设备频谱兼容性分析方法的原理,并通过2个实际工程案例,证明了该方法的有效性。最后,给出了使用该方法进行频谱分析的步骤和注意事项,如应对电磁干扰裕度留有余量。
