Vexcel Corporation proposes to develop the next generation ATR (Automatic Target Recognition) algorithms for use with foliage penetration (FOPEN) synthetic aperture radar. Vexcel has successfully completed the Phase I project sponsored by DARPA which prototyped advanced algorithms for use with Ultra-Wide bank (UWB) SAR data. One of the major challenges to working with this type of data is the number of dimensions available. These dimensions were enumerated during the Phase I portion of the work. A set of algorithms which exploited these dimensions were prototyped and used to demonstrate the utility and applicability to the ATR problem using real UWB data of concealed militarily significant targets. We intend to extend this analysis to all the major dimensions including combining frequency filtering, polarimetry, and interferometry to advance the state-of-the-art ATR performance. Phase II will perform in-depth analysis and EM modeling analysis, together with algorithm refinement and software implementation. The Phase II algorithms will be coded within the Khoros environment, and will be designed to be integrated easily into existing ATR software test beds. In addition to the ATR problem, there are significant civilian problems that may be addressed with this technology. We will use the GeoSAR system as a baseline "next generation" civilian sensor. GeoSAR is a civilian SAR system being developed by the state of California, which will include interferometric, polarimetric, and simultaneous multi-frequency capabilities. We intend to work closely with the California Department of Conservation to identify and develop the software tools which will be of the greatest value to this market. We envision a suite of software which will be integrated and offered to the commercial market within a major software package such as PCI or ERDAS.
