Abstract
The present invention allows quick detection of actual hazardous windshears while ignoring the effects of normal turbulence. A system according to one aspect of the present invention comprises a signal processor configured to determine a presence of hazardous windshear based on: (a) whether a measured windshear is beyond a first predetermined threshold, and (b) whether a measured turbulence level is beyond a second predetermined threshold.

18. A system comprising:
-
(1) a first filter configured to; (a) receive a windshear measurement; and (b) provide a filtered windshear measurement based on the windshear measurement; (2) a second filter configured to; (a) receive a modified windshear measurement; and (b) provide a filtered modified windshear measurement based on the modified windshear measurement; and (3) a windshear detection system in communication with the first filter and the second filter, the windshear detection system configured to provide a windshear alert based on the filtered windshear measurement and the filtered modified windshear measurement, wherein the windshear measurement corresponds to a horizontal shear measurement and a vertical shear measurement, wherein the filtered windshear measurement corresponds to a filtered horizontal shear measurement and a filtered vertical shear measurement, and wherein the windshear detection system is configured to; (a) detect, based on the filtered horizontal shear measurement and the filtered modified horizontal shear measurement, a presence of at least one of a headwind shear and a tailwind shear; and (b) detect, based on the filtered vertical shear measurement and the filtered modified vertical shear measurement, a presence of at least one of an updraft shear and a downdraft shear. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A method comprising:
-
(a) receiving, by a first filter, a windshear measurement; and (b) providing, by the first filter, a filtered windshear measurement based on the windshear measurement; (c) receiving, by a second filter, a modified windshear measurement; and (d) providing, by the second filter, a filtered modified windshear measurement based on the modified windshear measurement; and (e) providing a windshear alert based on the filtered windshear measurement and the filtered modified windshear measurement, wherein the windshear measurement corresponds to a horizontal shear measurement and a vertical shear measurement, wherein the filtered windshear measurement corresponds to a filtered horizontal shear measurement and a filtered vertical shear measurement, the method further comprising; (a) detecting, based on the filtered horizontal shear measurement and the filtered modified horizontal shear measurement, a presence of at least one of a headwind shear and a tailwind shear; and (b) detecting, based on the filtered vertical shear measurement and the filtered modified vertical shear measurement, a presence of at least one of an updraft shear and a downdraft shear. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37)
