Pole Splitting algorithm for UWB breast cancer imaging

In this paper, microwave breast cancer detection is investigated using Ultra-Wide Band (UWB) radar imaging. New approach for calibrating the received signals Pole Splitting is proposed for imaging. This approach is based on Estimation of Signal Parameters via Rotational Invariance Techniques (ESPRIT). The CST software simulation tool made for simulating the electromagnetic propagation through different mediums is used. Numerical phantom with complicated structures that uses the dispersive dielectric properties of the breast tissues has been developed for investigating the proposed approach and comparing it with the conventional averaging approach. The results show improvement in the detection using the proposed Pole Splitting approach compared with the conventional averaging approach.
