Abstract
A multi-stage Synthetic Aperture Radar (SAR) Automatic Target Recognition (ATR) system is analyzed across images of various pixel areas achieved by both square and non-square resolution. Non-square resolution offers the ability to achieve finer resolution in the range or cross-range direction with a corresponding degradation of resolution in the cross-range or range direction, respectively. The algorithms examined include a standard 2-parameter Constant False Alarm Rate (CFAR) detection stage, a discrimination stage, and a template-based classification stage. Performance for each stage with respect to both pixel area and square versus non-square resolution is shown via cascaded Receiver Operating Characteristic (ROC) curves. The results indicate that, for fixed pixel areas, non-square resolution imagery can achieve statistically similar performance to square pixel resolution imagery in a multi-stage SAR ATR system.
