Paper Abstract

A modified phase-encoded fringe-adjusted joint transform correlation technique is proposed for multiple target detection, where two joint power spectrums (JPS) are formulated utilizing a random phase mask and phase shifted random phase mask to the reference image separately. The final JPS is the difference between the phase encoded and shifted phase encoded JPS which is multiplied by the phase mask before applying the inverse Fourier transform to yield the correlation output. This technique ensures better utilization of the input/output plane space bandwidth product by yielding one delta function like correlation peak for each desired target object and no peak for non-target objects. The proposed technique can effectively detect any number of targets from noise free or noisy input scenes without changing the system parameters and without any degradation of performance. Computer simulation results verify the performance of the proposed technique.
