Abstract
Electromagnetic ultra-wideband (UWB) sensing and imaging provide perspectives for early-stage breast cancer detection. This paper deals with practical chal- lenges of real measurements. We present an experimental setup for breast phantom trials based on M-sequence radar technology and short active dipole antennas. It com- bines short impulse responses, appropriate fidelity and very small antenna dimension and allows array construc- tion with sufficient number of antennas around the breast. The basic approach and obtained imaging results are pre- sented. Furthermore, in this extended paper version con- tinuative development steps are described and measure- ment results reflecting specific performance aspects are discussed.
