Abstract

This paper presents a multi-wavelength algorithm that utilizes the weighted mean of all possible DIAL pairs. The weights are a function of the differential absorption coefficient between the DIAL pairs. The algorithm is shown to have greater sensitivity and robustness than two- wavelength DIAL. In addition, an algorithm for estimating the column content (CL) in the presence of multiple vapors is described. The algorithm iteratively fits the lidar equation to the data by adjusting the CL of each vapor of interest. Results are shown using topographic chamber test data collected in Dugway Proving Ground in 1996 using our frequency-agile lidar sensor.
