某型机载宽频带天线罩电气性能的测试研究

对2～18GHz的宽频带天线罩进行了测试研究,给出了天线罩电性能参数中的透波率和插入相位移的理论分析,并结合实际测量的数据进行了研究。测量结果表明,A夹层天线罩结构具有更好的透波性能,薄壁结构具有较均匀的插入相位移特性。在约束插入相位移的前提下,非对称夹层结构在透波性能、重量、抗弯刚度、抗弯强度方面更具优势。

Test Research on an Airborne Broadband Radome Electric Property

In this paper,a broadband radome from 2 to 18GHz is tested and researched.The paper presents theoretical analysis about the transmission efficiency and insertion phase delay of electrical performance of radome.It is reserched with the the actual testing data.The research results indicate that A sandwich radome has better transmission efficiency,and solid wall radome has better insertion phase delay.In the precondition of constrained insertion phase delay,unsymmetrical sandwich radome has advantages in transmission efficiency,weight,flexural rigidity and flexural strength.
