OSI proposes to develop a wake vortex detection system including a group of double-ended and single-ended optical scintillometers properly deployed in the airfield to measure ground and near ground crosswind, turbulence, and wake vortex using atmospheric turbulence-induced optical scintillations. As part of efforts, OSI also proposes to develop a single-ended optical scintillometer, together with a retro-reflector, for the measurement of near ground real-time crosswind and wake vortex. OSI will perform system analysis and design of the proposed system to detect occurrences, location, magnitude, and persistence of wake turbulence. With the simultaneous measurements of crosswind and turbulence, the sensor system is also able to forecast the arrival time of the airplane generated wake vortex drifting to a nearby runway.
