In this paper we present numerical results of contrast-enhanced breast imaging using ultra-wideband microwave radar system. Due to low contrast in electrical properties between dense breast tissues and malignant tissues, tumor detection using microwave might be extremely challenging. To overcome this problem, we propose here a radar imaging technique based on a localized contrast enhancement. Our results show that microwave contrast agents able of changing an effective dielectric constant of cancerous tissues by only 1% would greatly improve imaging performance.
