摘要
研究了带罩天线电磁辐射特性分析的口径积分-表面积分法,在罩外表面电磁流积分过程中,引入Gordon公式将罩面单元上的均匀相位分布修正为更贴近实际的线性分布,通过具体算例对改进方法的有效性进行了验证,计算结果表明,改进方法显著提高了带罩天线辐射方向图的计算效率和精度。
Aperture integration-surface integration algorithm is studied, which is used to analyze the electromagnetic radi- ation properties of radome-enclosed antenna. In the course of surface integration, uniform phase is replaced by linear phase with introducing Gordon formula, as the linear phase is more close to the real situation of radome surface. The validity of the improved algorithm is confirmed by a simple numerical example, and the simulation results show the efficiency and precision of radiation pattern of radome^enclosed antenna are raised greatly by using improved algorithm.
