Improved target detection using polarization-enhanced fringe-adjusted joint-transform correlation

We introduce novel optoelectronic target detection technique using polarization enhancement. Images correspond to elements of Stokes vector imagery are introduced as input scenes to the fringe-adjusted joint-transform correlator. Our results show excellent improvement in performance parameters. Both computer simulation and experimental results are presented in support of the proposed technique.
