Abstract

Three-dimensional (3D) microwave imaging in very dispersive media using a phase shift and sum (PSAS) algorithm is presented. The phase shift and amplitude attenuation within the dispersive media are compensated individually for each frequency component and then integrated to calculate the pixel values in the region of interest (ROI). Therefore, the multi-speed and multipath issue when an ultra-wide band (UWB) signal propagates in the dispersive media is overcome. The current approach is validated by lab-collected data using our self-developed 3-D UWB microwave measurement system. Image results are compared with prior arts at the end of this paper.
