摘　　要：根据透波盖透波性能要求,对透波盖所用材料及结构进行了设计。对设计制造的透波盖进行了强度有限元分析和结构抗压试验。强度分析和结构抗压试验结果相一致且满足透波盖的强度要求。为验证透波盖的透波性能,对其进行了透波检测,检测结果表明:透波盖在其两个工作频段内平均衰减分别为1.366 dB和1.588 dB,折合透波率86%和83%,满足透波性能设计要求。The materials and the structure of electromagnetic window lid were designed based on the requirements of wave permeance property. The designed lid was analyzed in strength by FEM and the manufactured one was tested in compressive strength. The result of strength analysis is consistent with that of compressive strength test, and meets the requirements of the lid strength. The wave permenance property test of electromagnetic window lid was also carried out. The delected result shows that the average attenuations of the penetrant signals in two frequency channel through the lid are 1. 366 dB and 1. 588 dB, respectively, and the corresponding wave permeance rates are 86 % and 83 %, respectively; the selected material can meet the requirements of wave permeance property.
