摘要

频率选择表面雷达罩能有效提高飞行武器的隐身性能，而复杂不可展开曲面上频率选择表面的加工存在技术难题。本文利用CST仿真软件，分析了基于Y-型单元结构的二维无限大频率选择表面的电磁传输特性，同时构建三维雷达罩内置相控阵天线模型，分析了不同扫描角度下曲面雷达罩的透射率和瞄准误差，从理论上论证了方案的可行性。在此基础上，提出了一种基于多自由度激光机器人与旋转台联动的一体化曲面厚屏频率选择表面雷达罩加工方案。微波暗室测试结果表明，制备的共形曲面FSS雷达罩带内透射率达到80%左右，带外透射率低于10%，展示了良好的电磁滤波特性。这种工艺能够满足各种大型共形曲面FSS雷达罩的一体化加工需求。

Abstract

Frequency Selective Surface(FSS) radomes can effectively improve the stealth performance of flying weapons. However

it is difficult to fabricate frequency selectivity on complex non-expandable surfaces. In this paper

CST simulation software was used to analyze the electromagnetic transmission characteristics of a two-dimensional infinitely large frequency selective surface

which is based on an array of Y-shaped unit structures. A 3-dimensional radome model with a built-in phased array antenna was employed to simultaneously analyze the transmittances and aiming errors at different scanning angles

to theoretically demonstrate the feasibility of the approach. Then

based on the linkage control of a multi-degree-of-freedom laser robot and a rotary table

an integrated approach was proposed to fabricate a thick-screen frequency selective surface radome. The results from tests conducted in a microwave anechoic chamber show that the prepared conformal FSS radome has a transmittance of about 80% and an out-of-band transmittance of less than 10%

demonstrating good electromagnetic filtering characteristics. This method can be used to fabricate a variety of large conformal FSS radomes.
