Abstract :
A low-cost, portable and reconfigurable Software Defined Radar (SDRadar) based is proposed for medical imaging. The proposed system can replace the commercial VNA, which is currently used in experimental microwave imaging systems. The proposed SDRadar has the capability to produce synthetic stepped-frequency continuous wave, frequency modulated continuous waveforms (FMCW) and pseudo random noise waveforms that can be used for non-linear and time variant medium. This will lead to a vital opportunity to improve the time, resolutions and accuracy in microwave-based medical imaging. Furthermore, the proposed device with hybrid waveforms can be designed for better imaging of complex human tissues.
