The long term goals of the Generic Lidar Model GLM are to create a real-time software package which can predict and visually simulate the performance of any Lidar system and to allow a user to vary environmentalsystem specifics in an interactive mode. In addition to facilitating quick sensitivity analysis of important system and environmental parameters on system performance, the synergy of interactivity and fast execution speed will also allow the model to be used as an engineering tool to evaluate or suggest system enhancements in a quasi-video mode. This synergy will also allow the creation of an innovative, interactive training tool which will provide valuable experience for Navy personnel without the need for expensive deployment at sea of existing and emerging Lidar systems. By itself, the fast execution speed will allow the software package to be used as part of a guidance subsystem to help select a Lidar system platforms altitude and perhaps control some of the systems adjustable parameters i.e., receiver aperture as it searches a particular area of the ocean or coastal environment. Overall objectives proposed for FY98 were to extend the monostatic geometry of GLM 1.0 to a bistatic one so that a laser line scanning system could be modeled, to extend backscattering calculations to a bistatic system, to allow for a horizontally layered atmosphere as was done for the water column, to include the effects of the airwater interface on imaging systems, to divorce the receiver gate from the target, to incorporate the effects of target height on Lidar returns, to initiate the validation of the GLM modules and to create a user-friendly, interactive GUI which can run on a PC.
