摘要 运用四端网络理论研究盐雾沉积层对A夹层天线罩板块电性能的影响,得到相应的功率透射系数和反射系数公式,并以某P/L波段雷达天线罩为例进行了计算机仿真.仿真结果表明,盐雾沉积层明显增大天线罩壁对雷达波的反射,形成的闪烁瓣会引起虚警;而且盐雾沉积层的吸收损耗会降低罩壁透射,形成雷达的附加盲区. Influence of salt-fog sediment on the electrical performance of A-sandwich radome panel by using four-port network theories is studied, and the power transmission and reflection coefficient of panel is formulized. As an example, the panel of a P/L-band radome is emulated. The results show that the salt-fog sediment increases the reflection of radome walls on radar wave evidently, which results in scintillating lobe and false alarm, and decreases the transmission of radome walls due to its absorption, consequently forming the larger blind zone of radar.
