A novel image reconstruction algorithm for early breast cancer detection via ultra wideband microwave signals is proposed. In this algorithm, the backscattered electric and magnetic intensities are measured and combined in a novel way to detect cancerous growth. Specifically, a power calculation is performed wherein Ey is multiplied by Hz after appropriate time shifting to create a focal point. Numerical results indicate successful localization of tumors as small as 3 mm in diameter.
