Objective: The purpose of this study is to develop accurate radar-based microwave imaging. Method: A portable radar-based detector is placed on an excised breast tissue of total mastectomy. Measurements are conducted twice with different orientations for the breast. A two-stage rotational clutter suppression (TSR) algorithm is carried out for the multi-static rotational configuration of the radar-detector. It consists of a signal selection and an adaptive filtering. Dot product is carried out for the two sets of confocal images measured at different orientations to remove clutters. Conclusion: The dot product of two confocal images with different orientations can reconstruct more accurate images than conventional confocal images. It can improve not only image contrast but also the accuracy of tumor location.
