A digital simulation of an optical matched filter is described. Two important aspects of the optical device are investigated using the digital techniques. The first study involves the preprocessing of the image prior to performing the analog matched filtering operation and the second the sensitivity of the device to rotation of the tar-get. These studies are carried out using a military target in common scenes such as villages, woodlands, and roads.
