The Application of Multi-look in UWB Microwave Imaging for Early Breast Cancer Detection Using Hemispherical Breast Model.
In UWB microwave imaging for early breast cancer detection, energy allocation to each tumor may be unequally when using single-look method, thus some of the targets may not be detected when multi-tumors exist. In this paper, we put forward a multi-look method: the source was set at eight difference places and eight groups of back-scattered signals were achieved by receiving antennas, the signals of each group were processed and results were added together. Theoretical analysis and numerical simulation show that multi-look method can not only reduce the clutters in imaging results but also detect all tumors more efficiently, and it is better than single-look method.
