Coherent summation of monostatic radar signals

Microwave breast imaging techniques are beginning to mature, with a number of systems being tested on large patient cohorts. As more data become available there are still many questions to answer about the relationship between the signals, the images, and the physiology. This paper explores the influence of various subsets of signals on the final image, and concludes that coherent summation of indirect and distant signals may be as significant to image accuracy as the contributions from signals containing strong responses.
