　　Breast tumor microwave sensor system (BRATUMASS) obtains the maximum reflection wave of breast tumor through the method of slot step frequency which uses radar system approach of frequency modulation interrupted continuous-wave.Wavepath-eifference between direct and reflected wave can be calculated by frequency component outputted with zero intermediate frequency signal.Dielectric properties of relevant breast tissue are inverted by energy distribution of the frequency output with zero intermediate frequency signal.We use Fourier diffraction and sagittal iterative reconstruction algorithm to determine the location of tumor,and confirm the feasibility of breast tumor microwave sensor system by clinical experiment.
