Abstract

The idealized performance of a direct-detection differential absorption lidar (DIAL) with an atmospheric backscatter reference has been previously formulated using a radar range equation for meteorological echoes. Performance of several systems is describe here under the assumptions of non- Gaussian speckle and log-normal atmospheric differential backscatter noise. Performance evaluations are presented in detail for a NO₂ detection system. Discussions on the preferred wavelengths for candidate gases, and a review of a new laser radar DIAL performance equation are presented.
