Dual-Receiver Turbulence LIDAR

To address the Air Force need for a sensor capable of remotely measuring optical turbulence in surrounding air. Intellisense Systems Inc. (ISI) proposes to continue developing the new Dual-Receiver Turbulence LIDAR (DReTL) proven feasible in Phase I. DReTL is based on the light backscattering amplification effect in a turbulent atmosphere, which is directly related to the magnitude of the refractive index structure parameter. The man-portable, compact, eye-safe DReTL will be capable of operating automatically 24/7 and providing the distribution of the refractive index structure parameter along its line of sight at a range of up to 10 km. A simple mechanical scanning mechanism will allow for the DReTL to be pointed in any direction in the hemisphere and collect volumetric data on the distribution of optical turbulence. Iridium-satellite-based secured data transmission channels will connect the DReTL with the Air Force Weather Enterprise. In Phase II, ISI will design the DReTL prototype and will prove its usefulness to the Air Force by testing its operation in real operational conditions while comparing the results of turbulence measurements with those of a calibrated turbulence sensor.
