چکیده :

In this paper, we propose a method for correcting potential errors in prior boundary information used in the microwave imaging process. Assuming that the boundary distortion follows a predefined distribution described by a limited number of parameters, the displacement of different points on the boundary can be related to each other. Using the analysis of the scattered fields sensitivity with respect to the changes in location of the boundary nodes in finite element method, the shape reconstruction problem is solved. The proposed method was investigated by a 2D simulation, and the results show that the boundary error can be corrected effectively.
