Abstract

We present a model-based inversion scheme to reconstruct 3D targets from microwave measured data. As a complementary algorithm to the pixel-based inversion algorithms, the model-based inversion algorithm employs much less unknowns by only inverting the parameters that determine the shape and material properties of the targets. The model-based inversion algorithm can also help to reduce the non-uniqueness in the inversion process. Numerical examples show that it can reconstruct 3D targets with good accuracy and efficiency.
