Abstract :
A three-dimensional finite-difference time-domain (FDTD) breast cancer detection model with antenna consideration is presented in this paper. The antenna structure is completely modeled using a resistive voltage source (RVS) as the excitation. The derivation of the updating equations for RVS is described in detail. A UWB antenna is simulated and the scattering parameters show the antenna performance. The simulation detection is carried out using a 3×3 antenna array. Double constrained robust Capon beamforming algorithm is employed to reconstruct the breast image and the correct information of the tumor is shown in the imaging result.
