The wind shear alert system is based upon a network of remote sensor stations placed near runways throughout the geographic area covered by an airport. An airport configuration file supplies numerous parameters related to the geometry and geography of the airport, as well as threshold values for divergence phenomena in the form of microbursts. Selected pairs, edges, and triples, triangles, of said network are monitored specifically to detect a divergence. Data from the various remote sensor stations is filtered to remove short term effects and adjust for missing data. A network mean is computed to which wind field measurement data and divergence analysis is compared. If a divergence in the form of a microburst or generic wind shear is detected, then the relative magnitude of the loss or gain in head wind to approaching aircraft is determined, as well as the location of the head wind. Alarm messages are issued to air traffic controller display screens which are then relayed to the pilot of an arriving or departing aircraft.Other References
