Ultrawideband Microwave RADAR, Sachbücher

Today, non-destructive electromagnetic imaging is a key technology. Its applications include early detection of cancer, fault detection in building materials, sub-surface characterization of the soil, and landmine detection. This book follows a marked experimental approach. It describes the design of an antenna array RADAR prototype able to acquire data and perform beamforming within the [2-4] GHz frequency band. On one hand, qualitative imaging experiments have been performed. Time Reversal, as well as DORT and TR-MUSIC methods, has been applied to detect and localize scattering objects both in free-space and reverberating media. On the other hand, the prototype has been used for quantitative inverse scattering in very aspect-limited configurations. For this purpose, a non-linearized iterative algorithm has been adapted to the experimental setup through an accurate calibration procedure.
