Abstract :
In this paper, we propose an UWB based multi static imaging technique which seeks to produce images and localize malignant breast tissues by processing the backscattered ultra-wideband (UWB) signals from numerical models of both tumor and normal breast tissues. We demonstrate that standard capon beamforming (SCB) combined with time-of-arrival (TOA) could give some reasonable results for imaging and localisation of breast cancer. The results are based on the ideal case; however it provided a direction for future improvements.
