摘要：

The distorted Born iterative method (DBIM) is used to solve two-dimensional inverse scattering problems. The purpose of this algorithm is to provide another general method to solve the two-dimensional imaging problem when the Born and the Rytov approximations break down. Numerical simulations are performed using the distorted Born iterative method and the method proposed in our previous paper [called the Born iterative method (BIM)] for several cases where the conditions for the first-order Born approximation are not satisfied. The results show that each method has its advantages. The distorted Born iterative method shows faster convergence rate compared to the Born iterative method, while the Born iterative method is more robust to noise contamination compared to the distorted Born iterative method. © 1990 IEEE
