摘要

通过将压缩传感理论引入矩方法，可以快速解决大入射角电磁散射问题，其主要计算复杂度由两部分组成：少量矩阵方程计算和原始感应电流恢复。为进一步改进该方法，本文提出了一种新颖的测量矩阵构造方案。在测量矩阵的帮助下，可以得到稀疏的感应矩阵，因此恢复的计算成本至少可以减少一半。本文详细介绍了该方案，并通过计算复杂度分析和数值实验证明了其有效性。

An acceleration method employing sparse sensing matrix for fast analysis of the wide-angle electromagnetic problems based on compressive sensing

The electromagnetic scattering problem over a wide incident angle can be rapidly solved by introducing the compressive sensing theory into the method of moments, whose main computational complexity is comprised of two parts: a few calculations of matrix equations and the recovery of original induced currents. To further improve the method, a novel construction scheme of measurement matrix is proposed in this paper. With the help of the measurement matrix, one can obtain a sparse sensing matrix, and consequently the computational cost for recovery can be reduced by at least half. The scheme is described in detail, and the analysis of computational complexity and numerical experiments are provided to demonstrate the effectiveness.
