Abstract:
A tomographic method for objectively determining extinction and backscatter using a single, scanning wavelength lidar is outlined. In the theoretical analysis, the scattering media is observed from different directions by a lidar which is either moved or observed the structures as they drift past the lidar. A matrix equation is developed and tested by randomly selecting extinction and backscatter values on a 5 by 5 grid. Measurement and turbulence induced errors are modeled and the measurement accuracies are assessed. Results for the theoretical calculations suggest that the method would provide accurate results for a scanning airborne lidar, but not from a scanning systems that does not move.
