Autonomous lidar wind field sensor: performance predictions

Solid-state coherent Doppler lidar sensors operating at the eyesafe 2 micrometers wavelength have experienced rapid development over the past five years. Several ground-based and airborne systems have been successfully demonstrated. CTI is currently making significant strides toward the development of an autonomous, modest-cost wind field sensor for boundary-layer profiling. High spatial resolution 3D coverage for several kilometers around the lidar location will be possible at update rates of about a minute-- depending on the scan volume and grid size. This paper summarizes the results of detailed sensor performance modeling for the boundary layer profiler and discusses preliminary scan concepts and issues.
