探讨二维介质柱微波成像的计算机模拟。其基本思想是从体等效原理出发，得到积分方程并由此积分方程出发，利用矩量法，得到矩阵方程形式的反演方程。除方程的病态，文中采用了基于最小二来原理的正则化方法。为了尽量与实际情况接近，文中推导了噪声与反演结果之间的关系，初步考虑了噪声对反演结果的影响。
To discuss the computer simulation of two-dimensional media column microwave imaging. The basic idea is to start from the body equivalent principle, get the integral equation and proceed from the integral equation, and use the method of moment to get the inversion equation of matrix equation. In addition to the ill-posed equations, the regularization method based on least-squares principle is adopted in this paper. In order to get as close to the actual situation as possible, the relationship between noise and inversion results is deduced and the influence of noise on the inversion results is preliminarily considered.
