| 摘 要： | 提出了一种采用s参数法结合CST-MS软件进行航天器屏蔽度仿真分析和预测的方法。在航天器舱体结构内的发射天线和舱体结构外的接收天线处分别设置端口,通过计算端口间的s参数来分析计算舱体结构的屏蔽度,并将仿真分析结果与实测结果进行对比。对比结果表明,仿真计算结果与实测验证结果基本上是一致的,充分验证了采用s参数法结合CST-MS软件对屏蔽度仿真分析,具有很好的实用性和计算精度。这种方法应用于航天器设备级和系统级,能够显著降低航天器电磁兼容性(EMC)分析的难度,并能在一定程度上简化航天器前期设计中EMC试验验证的需求。

| Abstract: | The paper proposes a method of using s-parameters with CST-MS software to make simulation analysis and prediction of spacecraft shielding degree, by calculating s-parameters be- tween the ports which are separately set at the transmitting antenna inside spacecraft shielding structure and at the receiving antenna outside the structure, and contrasts simulation result with the test result. The result shows that the method using s-parameters with CST-MS software to simulate and analyze the shielding degree is universal, practical and precise, which can be used in both spacecraft equipment level and system level and make EMC analysis of spacecraft easier or even simplify some tests in the spacecraft EMC design. |
