摘要/Abstract

摘要： 针对反辐射武器对雷达构成的威胁，设计了一种既能够直接防御反辐射武器近炸毁伤，又能保持优异透波性能的防弹天线罩夹芯板块结构。对不同厚度的超高分子量聚乙烯(UHMWPE)层合板进行弹道侵彻实验，确定将UHMWPE层合板作为夹芯结构的防弹层。通过电磁性能优化的方法确定夹芯结构的结构参数，并对其电磁性能进行了理论分析。弹道实验和电磁性能测试结果表明，该夹芯结构能够防御某型反辐射导弹在15 m处爆炸产生的破片冲击，并且在S波段的平均透波率（功率传输系数）不低于97.8%，平均值达到了98.6%。理论计算结果和实验结果表明文中提出的防弹天线罩夹芯结构设计方法是有效的。

Abstract: A sandwich structure with high transmissivity for ballistic-resistant radome was designed to prevent a radar from impact produced by short distance explosion of anti-radiation weapon. Ultra-high molecular weight polyethylene (UHMWPE) laminate was determined as anti-penetration layer of sandwich structure by testing the ballistic penetration property of UHMWPE laminates with different thicknesses. The structure parameters were obtained by electromagnetic optimization, and the electromagnetic performance of designed sandwich was theoretically analyzed. Ballistic and electromagnetic test results show that the designed sandwich structure resists fragment impact produced by the explosion of a certain anti-radiation missile at 15m, with minimum transmissivity (power transmission coefficient) of 97.8% and average value of 98.6% at S band. The design method for sandwich structure of ballistic-resistant radome has been proven to be reliable by theoretical and experimental results.

Key words: solid mechanics, ballistic resistance, radome, sandwich structure, ultra-high molecular weight polyethylene
