非均匀介质下地形抛物方程的反问题
Inverse Problem of Terrain Parabolic Equation in Non-uniform Medium
摘要
Abstract
We established an optimization model for the refractive index inversion problem in the terrain parabolic equation based on the framework of optimal control theory.Firstly,through rigorous mathematical analysis,we proved the existence of minimum value for the objective functional and its necessary conditions.Secondly,we proved the local uniqueness and stability of the minimum value to the problem.关键词
