Effects of various image enhancement techniques on FOPEN data

An investigation of FOPEN target discrimination performance is summarized using UHF SAR data gathered at Grayling, MI by the USA Navy's P-3 SAR Sensor. The fully polarimetric data are processed using polarimetric whitening; superresolution processing is then applied to enhance the resolution of the whitened data. Several superresolution approaches are investigated and target discrimination performance achieved using superresolution processing is quantified. Discriminator ROC curves showing probability of detection versus probability of false alarm are used to compare performance; an eigenvector-based superresolution approach is shown to provide the best performance improvement.
