Abstract

Synthetic Aperture Radar (SAR) image modeling tools are of high interest to Automatic Target Recognition (ATR) algorithm evaluation because they allow the testing of ATRs over a wider range of extended operating conditions (EOCs). Typical EOCs include target aspect, target configuration, target obscuration, and background terrain variations. Since the phenomenology fidelity of the synthetic prediction techniques is critical for ATR evaluation, metric development for complex scene prediction is needed for accurate ATR performance estimation. An image domain hybrid prediction technique involves the insertion of a synthetic target chip into a measured image background. Targets in terrain scenes will be predicted and compared with similar measured data scenarios. Shadow region histograms and terrain region histograms will be used to develop some first generation metrics for phenomenology validation of hybrid SAR prediction techniques.
