Paper Abstract

The real-time simulation of broken and distorted images of a submerged target observed through a random realization of wind roughened sea surface produced by airborne gating imaging lidar is presented. The user is allowed to watch the sequence of images at the computer screen, which the lidar operator vies sat the TC screens of an operating airborne imaging lidar. Th inclusion of all types of noise as well as spatial correlation of receiver noise and noise due to a windy roughened sea surface with detailed treatment of seawater scattering provides a very realistic model. Two image processing techniques to deal with actual images - Matched Filter and Optimal Integration - are compared as to signal-to-noise ratio and probability of detection. Optimal Integration is appropriate for use by an experienced lidar operator.
