Abstract:

An imaging method based on the nonlinear contrast source inversion (CSI) algorithm is applied to reconstruct the 3-D dielectric targets in an anechoic chamber. Extended approaches, such as regularization and frequency hopping (FH), are used in this method. The 3-D experimental microwave data are measured in a multi-frequency multi-bistatic mode. The inversion results, presented and compared for the 3-D experimental microwave data, verify the feasibility and accuracy of the extended CSI algorithm, which has promising application prospects in 3-D microwave imaging.
