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.

1 more element
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.
