Abstract
Vexcel Corporation, in cooperation with Lockheed Martin Tactical Defense Systems, proposes to identify and develop next generation algorithms for automatic target recognition (ATR) using polarimetric ultra-wideband (UWB) synthetic aperature radar (SAR) data. Specifically, we will address the potential of combining the polarimetric aspects of the foliage penetrating (FOPEN) SARs with interferometric technology. Expected benefits will be improved ATR algorithms and new techniques for mapping terrain under trees, as well as potentially measuring some parameters related to tree height and density. Sensors capable of producing such data are expected to become operational in the near future for both military and civilian applications. While there has been a considerable amount of research conducted in the area of ATR using SAR data, most has focused on the application to more traditional military radar systems, specifically higher frequency systems. Some research into polarimetric aspects of the data have been carried out, as well as investigations into UWB ATR applications. To exploit the new dimensions of this data, we impose important calibration requirements on the sensor data. Specifically, we will investigate the use of calibrated phase and amplitude information available in the polarimetric scattering matrix measurements. This is required to perform accurate polarization synthesis. Throughout this work, we will focus on the eventual operational implementation of the identified new algorithms. Specific real-time applications to UWB sensors will serve as examples.
