| 摘 要： | 采用基于非线性对比源反演算法的成像方法来重建放置在微波暗室内的三维电介质目标。在成像方法中采用正则化方法和频率跳变(frequency hopping, FH)方法等扩展手段。三维实测微波数据的实验设置是多频率、多收发分置的。三维实测微波数据的重建结果验证了基于对比源反演算法的扩展成像方法在三维微波成像中应用的可行性和精确性，是一种有应用前景的解决三维微波成像问题的处理方法。

| 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. |
