Abstract

Ultra-wideband radar imaging is a promising modality of imaging for breast cancer detection, based on the dielectric contrast between healthy and pathological tissues. Its aim is to create a map of microwave scattering, and has already proven encouraging results. Unfortunately, the tumor extraction procedure used for reconstruction of the scattering volume leads to the appearance of an artifact called twin target, where a single tumor is expected. In this paper, a signal processing technique is presented to remove this twin target and enhance the contrast of the final image. The radar system and image formation algorithm are first described to explain the origin of the twin target. Experimental data are then acquired and processed by our correction algorithm, demonstrating its ability to fix the twin target issue.
