Analysis of Lidar Utility for Characterizing Battlefield Environments
PACIFIC-SIERRA RESEARCH CORP LOS ANGELES CA
Pagination or Media Count:
The use of lidar to infer information about battlefield obscurants such as smoke and dust has received considerable attention in recent years. State-of-the-art lidars can provide relative transmission and spatial concentration data for three dimensional obscurant clouds. In spite of this, the theoretical models necessary for interpreting the lidar return have not contained dependencies on all of the relevant transmitter and receiver parameters, and have been almost entirely limited to first order scatter. Since the conditions for these models to be valid are not always met, there appeared to be a need for a more fundamental theoretical basis which would reproduce the usual equations as an approximation and would give a clear basis for understanding their limitations and generalizing them as required. Providing this model was one of the primary aims of the contract.
