摘要

为求解电大尺寸载体天线间的宽带干扰耦合度

建立了天线间干扰耦合分析模型

提出了自适应多层快速多极子算法作为求解该耦合分析模型的核心算法.该算法将阻抗积分表达式中的基函数和权函数分别用不同空间位置上的Dirac函数展开

使阻抗积分的计算得到大大简化

所有转移过程可由快速傅里叶变换计算完成

应用波形渐进估计技术计算载体表面及天线上的宽带电流值

最后结合微波二端口网络理论求得天线间的宽带耦合度.数值实验和实测结果证明

在精度相等的前提下

所提出的快速分析方法比传统快速分析方法的计算效率和存储效率均提高了30%左右.

Abstract

A coupling model of antenna and an adaptive multilevel fast multipole algorithm(AMLFMA)are introduced for the analysis of the broad band coupling of antennae on electrically large targets. By expanding the basis functions and weight functions with Dirac functions in different spatial position

the impedance integration calculation of the AMLFMA can be simplified and all the transformation procedure can be calculated by fast Fourier transformation. Combining AMLFMA with asymptotic

wave form evaluation technique(AWE)the broad band currents on antennae can be calculated rapidly. The broad band coupling of antennae can be calculated via microwave two ports theory. Numerical and experiment results show that the CPU time and memory needed for the analysis procedure using AMLFMA/AWE are less than MLFMA/AWE method by 30% under the same precision.
