Summary:
A radar-based breast cancer detection system was developed using a CMOS impulse transmitter circuit and an ultra-wideband (UWB) antenna array. The center frequency and the bandwidth of the antenna were 6 GHz and 12.5 GHz, respectively. A 198 ps Gaussian monocycle pulse (GMP) was generated by the CMOS circuit and emitted by 4x4 planar slot antenna array. The three-dimensional image of a 10 mm x 10 mm tumor phantom buried at the depth of 20 mm in the breast adipose phantom was reconstructed by confocal imaging algorism.
