基于互易间隙原理产生的未知边界非线性不适定积分方程,提出了求解时谐波障碍物逆散射问题的一种新方法。这个积分方程可以通过线性化,即正则牛顿迭代来求解。给出了该方法的数学基础,并通过算例说明了该方法的可行性。
We present a novel solution method for inverse obstacle scattering problems for time-harmonic waves based on a pair of nonlinear and ill-posed integral equations for the unknown boundary that arises from the reciprocity gap principle. This integral equations can be solved by linearization, i.e., by regularized Newton iterations. We present a mathematical foundation of the method and illustrate its feasibility by numerical examples.
