Near-Real-Time Data Acquisition and Beamforming for UWB See-Through-Wall System

An ultra-wideband See-Through-Wall (STW) imaging radar system has been developed that could allow the acquisition and processing of the collected radar data in real-time or near-real-time environment. In this paper, we have compared the performance of various Synthetic Aperture Radar image formation methods, and we will demonstrate the wall-correction preliminary results. Additionally, the design of a near-real-time FPGA-based beamforming processor will be presented and samples of our theoretical and experimental collected data.
