摘　　要：天线罩网架散射是对天线罩电磁性能影响的主要因素,采用迭代感应场率算法对雷达天线罩金属网架散射特性进行了分析。阐述了迭代感应场率算法的基本理论,得到了天线罩网架的散射方向图,并提出了大规模网架杆件迭代计算的加速方法。结果表明,该算法计算结果与电磁仿真软件FEKO计算结果吻合良好,并较传统感应场率算法具有较高的计算精度。The scattering field of radome frame is the main factor influencing radome electromagnetic properties, which is analyzed using the interactive induced field ratio method （IIFR）. The basic theory of IIFR is expounded and the radome frame scattering pattern is obtained. Furthermore, the acceleration method of iterative calculation on large-scale frame grid is proposed. The results show that the result calculated by IIFR agrees well with that by electromagnetic simulation software FE- KO, and IIFR owns a higher calculation accuracy than traditional induction field ratio （IFR）.
