Abstract :
Weighted L2-norm edge preserving multiplicative regularization in conjunction with a 3D nonlinear time-domain inverse scattering technique has been used to reconstruct accurate three dimensional images with high resolution of unknown objects. Results show that this technique is capable to reconstruct contrasts of 2:1 and low ones as much as 10%.
