Optical and digital approaches to 2-D image processors each have their unique advantages and limitations. Hybrid systems have been proposed to utilize the best of both. An equally important manner in which the two approaches can complement each other is through a digital simulation of the optical system. This paper reviews some of the problems of matched filter correlator applications and illustrates how valid models for simulations can be generated. Comparisons of the digital simulation to the analog approach are made for detection problems using specific targets and terrains. The relative merits of each technique as well as ways in which the digital simulation may be used to assist in the optimal design of the analog system are discussed.
