Abstract :
Feasibility of a new microwave radar imaging system for early stage breast tumor detection using chirp pulse microwaves was investigated numerically. In the FDTD-based simulation, the basic idea of discriminating tumors from surrounding inhomogeneous breast tissues was verified and the effects of the bandwidth of CP-MBR on the resolution were examined by varying the frequency band from 2-3 GHz to 1-4 GHz.
