A new method for improving detection performance of modified amplitude-modulated joint transform correlators by using a smoothed amplitude-modulated filter (AMF) is proposed. Smoothing of the filter is done to reduce dependence of the detection performance on a threshold value. Simulation results show that recognitions of intratarget scenes can be optimized by using a single smoothed AMF generated at low threshold.
