Two types of direct-detection Doppler lidars are described: the multichannel spectral resolving approach and the edge technique approach. The two methods are compared in terms of fundamental sys- tem characteristics. The equations necessary to model the instruments and predict noise-limited performance are developed in forms that en- able an easy comparison of the methods. Using those equations, simu- lation results are presented to compare the performance of the receiver systems. Results are shown for both aerosol Doppler and molecular Doppler systems. Instrument design considerations are discussed to clarify the choice of realistic values for the model parameters. © 1998 Society of Photo-Optical Instrumentation Engineers.

A Doppler lidar for measuring winds in the middle atmosphere
TL;DR: In this paper, a Doppler Lidar is used to measure the wave-mean flow interaction in the middle atmosphere using Rayleigh scattering from air molecules, which is designed to cover the height range 25-60 km, where radars cannot operate.

Edge technique: theory and application to the lidar measurement of atmospheric wind.
TL;DR: The frequency shift measurement insensitive to both laser and filter frequency jitter and drift is shown to be insensitive to the laser width and shape for widths that are less than the half-width of the edge filter.

TL;DR: Coherent lidar/laser radar systems have been used for the remote measurement of atmospheric wind velocity since 1966 as discussed by the authors and have been applied to detection and tracking of aircraft wake vortices, measurement of airborne wind fields during the space shuttle takeoff and landing, airborne wind shear detection, ground-based airport microburst windshear monitoring, meteorological research, and environmental monitoring.
