چکیده :

Noniterative algorithms for solving inverse scattering problems are of great interest for their computational efficiency. Although their application is limited, they can enable fast and robust reconstructions possible. However, the resulting image has low accuracy. It is usually fed to an iterative algorithm as an initial guess to get the exact result. Increasing the accuracy of the noniterative algorithm output can improve this initial guess for faster convergence. It can even obviate the need for iteration in some cases. In this work, we incorporate spatial a priori information in the noniterative solution of inverse scattering problems. It is incorporated in modifying the regularization term. The results show that it can remarkably improve the accuracy of the reconstructed permittivity.
