Paper Abstract

Several metrics for quantifying the performance of fringe-adjusted joint transform correlator (JTC) technique are investigated in this paper. The criteria used for measuring the performance of fringe-adjusted JTC include peak sharpness, signal-to-clutter measure, distortion invariance, signal-to-noise ratio and a new metric called peak-to-background correlation energy is proposed in this paper. These metrics are used to estimate the reliability of signal detection in the input scene with respect to clutter, noise and other associated distortions. Detailed analysis and simulation results for quantifying the performance of fringe-adjusted JTC are presented.
