Abstract :
      Electromagnetic inverse scattering is the process of inferring the electrical and/or geometrical properties of the unknown objects in a region of interest from the measured field outside that region. It offers numerous civilian and military applications, i.e., radar imaging, remote sensing, geophysics exploration, medical imaging, antenna diagnostics, nondestructive testing, etc. 
     In this talk, after a brief overview of electromagnetic inverse scattering, I will present the recent progress on Ground Penetrating Radar (GPR) imaging and Through-the-Wall Radar imaging (TWRI) from the perspective of electromagnetic inverse scattering. GPR imaging and TWRI involves cross-disciplinary research in electromagnetic wave propagation, antenna and waveform design, radar system, image and signal processing. The talk will discuss MIMO GPR imaging, 3-D radar imaging through multilayered media, real-time processing for 2-D and 3-D TWRI, Compressive Sensing for radar imaging. It shows remarkable improvement over traditional imaging approaches in the above fields. Performance improvement and conditions of utilization of these emerging techniques for data analysis, acquisition, and processing are delineated and supported by full wave electromagnetic simulated data and experimentations.
