A hybrid analytic computer simulation approach is used to estimate centroid performance of laser radar images. This approach includes the statistical effects of shot-noise and speckle and provides the flexibility to model complex target geometry and surface scattering, image point spread response characteristics, and target glints. Results suggest that image edge effects have a pronounced impact on centroid accuracy. A bi-level threshold is shown to provide improved centroid stability over intensity and binary images.
