Paper Abstract

Graylevel patterns are used to identify the correlation discrimination performance of the phase-only filter (POF) and amplitude-modulated inverse filter (AMIF) . The correlation tests were repeated with Gaussian random noise added to the input signal. The computer simulation results show that the ANIF based correlator has better discrimination capability than that of the POF based correlator in the absence of noise as well as in the presence of Gaussion random noise over most of the practical range of noise variance. 1.
