Abstract

The image signal-to-noise ratio and statistical variance of image centroid estimates are derived for coherent heterodyne and homodyne laser radar images of extended diffuse targets. Both intensity and binary target images are studied. Binary image is shown generally to offer a more reliable estimate of the target centroid.
