B01: Inverse Scattering and Imaging (1) - In memory of Professor Karl Langenberg

Monday, August 18  08:00-09:20,  Room #19

Session Chairs: Matteo Pastorino, Ehud Heyman

Electromagnetic wave techniques, both active and passive, are gathering strong attention in sensing and imaging related to security applications. They include landmine detection, identification of intruders, finding human bodies in disaster events, vehicle collision avoidance, security checking at airports, etc. Used wavelength now ranges from radio to X-ray waves. One of recent driving forces is the use of UWB (Ultra Wideband) signals, which dramatically improves the range resolution, and thus extends the applicability of radar technique to targets with very short ranges, such as indoor and medical imaging. Many of these applications require super resolution and/or very fast computation in order to provide real time images with high quality and reliability. Advanced inverse scattering algorithms and imaging techniques are the key issues of the session. Theoretical investigations and studies aiming to other type of applications are of course welcome.
