| 英文摘要 | Two multifrequency imaging algorithms are presented for the reconstruction of unknown objects when only the intensity measurement of the total field is available using the phaseless data distorted rytov iterative method. the first one uses all the frequencies simultaneously to form a matrix equation and only deals with lossless objects. the second one can reconstruct both lossless and lossy objects, in which a low frequency is utilized to guarantee convergence. then the reconstructed result is used as the initial estimate for a higher frequency. repeat this process by gradually increasing the working frequency until high imaging quality is achieved. numerical and experimental results are presented to show the high efficiency of the proposed algorithms. |
