摘要
在矩量法基础上,通过波动方程的求解把泛函方程转换为代数方程。变形Born迭代算法解决了方程的非线性问题;TTLS正则化解决了解的稳定性。实验表明,运用空间域的层析成像方法,迭代过程中的计算量减少了,算法的应用范围得到了拓宽,在较强散射的情况下,反演较高的对比度。
On the basis of researching the method of moment, the functional equation is converted to algebraic equauon Dy solving me wave equauul,. The distorted Born iterative algorithm is used to solve the equation of nonlinear problem, and the stability of the solution is solved by using the truncated total least squares regularization method. Experimental results indicate that the above methods can be applied to the strong scattering field, can inversion high contrast and also have higher image quality.
