TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
We propose a 1.5um fiber-optic pulsed coherent lidar as a highly effective sensor sub-system for airborne wake-vortex hazard detection. The proposed design is based on a recently developed platform at Fibertek, for fiber-optic pulsed coherent lidar capable of 6km range, and operating at high pulse rate to give high-resolution spatial map and circulation strength, characteristic of typical wake-vortex signatures. The proposed system uses all COTS 1.5um fiber-optic component technology and COTS high-speed digital electronics, to provide a cost-effective system, that is amenable to rapid transition for field testing and adoption.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
(1a) Ground-based wake vortex hazard monitoring at airport terminal area take-off/landing interval optimization
(1b) Airborne wake-vortext hazard monitoring for pilot assistance, during landing in congested airports.

(2) Wind-shear turbulence monitoring

(3) Investigate & map atmospheric boundary layer dynamics for improved local weather scientific understanding, and local weather forecasting

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
(1) Wind vector sensor for aiding and/or extending Unmanned Aerial Vehicle (UAV) flight duration, for extended surveillance missions

(2) Tracking of hazardous aerosol plume detection, for providing advance warning to affected entities.
