提出了一种口径积分-表面积分和射线跟踪混合方法,分析了某大型雷达罩对SSR线天线及单元方向图的影响,给出了带罩天线方向图中直射瓣和反射瓣的矢量合成的解法,数值计算结果与实验数据符合较好.

In this paper, the hybrid method of aperture-integration and surface-integration technique with three dimension ray tracking technique is presented. By this method,the effects of a large airborne radome on SSR linear radiate array and element are analyzed. The solution to the vector superposition of direct lobe and reflection lobe in the antenna pattern with radome is given. The calculated result and the experiment one are good agreement.
