| 摘 要： | 基于线性分布细金属柱体的散射模型,用多极子展开求解电磁散射问题。以测量的散射场和计算散射场偏差为目标函数,将待优化变量设置为描述细金属柱体中心位置的向径和幅角,通过多相粒子群算法（MPP-SO）优化待优化变量,通过使目标函数达到最小值实现自由空间中线性分布的细金属柱体族的电磁成像。算例表明：MPPSO有较好的收敛性能和成像精度,以及较强的抗随机噪声干扰能力。

| Abstract: | A scattering model using a multiple expansion was used to solve the scattering problem for linear distribution of thin metallic cylinders in this paper.The error between measured scattering data and computed scattering data was considered as the object function.The center position of each thin metallic cylinder was denoted by polar coordinates parameters.The inverse scattering problem was transferred into a optimization problem by minimizing the object function with the polar coordinates parameters being op... |
