TWO NUMERICAL METHODS FOR ONE DIMENSIONAL ELECTROMAGNETIC INVERSE SCATTERING PROBLEM

Sheng Xianneng Zhou Ziengou Huang Shunji  
The paper calculates inverse scattering problem for two models of inhomogeneous layered media using numerical methods. The first problem is inversion of one dimensional discrete stritified inhomogeneous media terminated by a perfect conductor. Numerical method used in this model is parameter optimization techniques of variable scale The numerical results of performance index are 10~(-7). The second problem is inversion of one dimensional planar, continuously varying media. In this model the relaxation method is introduced to accelerate the iterative leap fiogging procedure. Calculating several examples the results show that the number of iterative time is reduced due to introduction of the relaxation method. In typical examples it can be reduced by three times.
