dc.description.abstractAn extended fractional Fourier transform (FRT) based fringe-adjusted joint transform correlator (JTC) for real-time target recognition applications has been implemented. In real-time situation, the input scene is captured using a charge-coupled device camera. The joint input images are fractional Fourier transformed and the joint power spectrum (JPS) has been recorded. Thus obtained JPS is multiplied by a pre-synthesized fringe-adjusted filter (FAF) to yield fractional fringe-adjusted JPS (FrFJPS). The FRT based fringe-adjusted JTC (FrFJTC) has been found to yield better results in comparison to the conventional fringe-adjusted JTC (FJTC). Three performance measure parameters; correlation peak intensity, peak-to-correlation energy and peak-to-sidelobe ratio have been calculated. Computer simulation and experimental results are presented.en_US
