摘要

针对一类正散射和逆散射问题，提出了一种新的高度并行算法。结果表明，该算法减少了现有算法所表现出的噪声传播，并产生与离散步长平方成正比的误差项。与传统算法不同，这个新公式解耦了给定层中的反射核。由于其解耦性，新公式完全消除了同一层中任意两点之间的任何误差传播。给出了数值算例来说明所提出的算法

An algorithm for a class of direct and inverse scattering problems

A novel, highly parallel algorithm for a class of direct and inverse scattering problems is proposed. It is shown that this algorithm reduces the noise propagation exhibited by the existing algorithms, and produces error terms that are proportional to the square of the discrete step size. Unlike the conventional algorithms, this new formulation decouples the reflection kernel in a given layer. Due to its decoupling nature, the new formulation completely eliminated any error propagation between any two points in the same layer. Numerical examples are presented to illustrate the proposed algorithm.<>
