Abstract

An airport incursion notification system includes a fiber optic configured as an interferometric sensor to detect noise and buried adjacent at least at select runways and taxiways of an airport. At least one interrogator unit is for determining the location of and classifying noises detected by the fiber optic. Indicators are present at least at select runway and taxiway intersections. A controller subsystem is responsive to the interrogator unit and is configured to activate one or more indicators if an incursion condition exists. Imaging and/or radar subsystems can also be employed.

Claims

1. An airport incursion notification system comprising:

a fiber optic cable configured as an interferometric sensor to detect noise and buried adjacent to one or more select runways of an airport;

at least one interrogator unit for determining the location of and classifying noises detected by the fiber optic;

indicators at least located at select runway and taxiway intersections; and

a controller subsystem responsive to the interrogator unit and configured to activate one or more said indicators if an incursion condition exists.

2. The system of claim 1 in which the fiber optic cable is set along opposite sides of said select runways.

3. The system of claim 1 in which the indicators include above ground warning lights.

4. The system of claim 1 in which the indicators include runway entrance lights.

5. The system of claim 1 in which the indicators include take off hold lights.

6. The system of claim 1 in which the indicators include runway intersection lights.

7. The system of claim 1 in which the indicators include precision approach path indicator lights.

8. The system of claim 1 in which an incursion condition includes a plane on a runway and said controller subsystem is configured to activate indicators at taxiways intersecting with said runway in response.

9. The system of claim 1 in which an incursion condition includes an object on a runway and the controller subsystem is configured to activate runway based indicators in response.

10. The system of claim 1 in which an incursion condition includes a plane on a taxiway intersecting a runway and a plane, vehicle or other object detected on said runway and said controller subsystem is configured to activate an indicator at the taxiway where it intersects the runway.

11. The system of claim 1 further including a fiber optic cable buried adjacent to at least one taxiway of the airport.

12. The system of claim 11 in which an incursion condition includes a plane or vehicle on one taxiway and a plane or vehicle on an intersecting taxiway and the controller subsystem is configured to activate an indicator at said taxiway intersection.

13. The system of claim 1 further including a high resolution imager.

14. The system of claim 13 in which the controller subsystem is further configured to activate the high resolution imager in response to an incursion condition.

15. The system of claim 1 further including a radar subsystem.

16. The system of claim 15 in which the radar subsystem includes a millimeter wave or X band radar subsystem.

17. The system of claim 15 in which the controller subsystem is configured to activate the radar subsystem in response to an incursion condition.

18. An airport system comprising:

an acoustic sensor subsystem set along one or more select runways of an airport;

indicators located at least at select runway and taxiway intersections; and

a controller subsystem responsive to the acoustic sensor subsystem and configured to activate one or more said indicators if an incursion condition exists.

19. The system of claim 18 in which the acoustic sensor subsystem is set alongside said one or more runways.

20. The system of claim 19 in which the acoustic sensor subsystem is buried alongside said one or more runways.

21. The system of claim 18 in which the acoustic sensing subsystem includes a fiber optic cable configured as an interferometric sensor.

22. The system of claim 21 in which the fiber optic cable is set on opposite sides of said one or more select runways.

23. The system of claim 21 in which the acoustic sensing subsystem further includes at least one interrogator unit configured to detect the location of and classify noises detected by the fiber optic cable.

24. The system of claim 18 in which the indicators include above ground warning lights.

25. The system of claim 18 in which the indicators include runway entrance lights.

26. The system of claim 18 in which the indicators include take off hold lights.

27. The system of claim 18 in which the indicators include runway intersection lights.

28. The system of claim 18 in which the indicators include precision approach path indicator lights.

29. The system of claim 18 in which an incursion condition includes a plane on a runway and said controller subsystem is configured to activate indicators at taxiways intersecting with said runway in response.

30. The system of claim 18 in which an incursion condition includes an object on a runway and the controller subsystem is configured to activate runway based indicators in response.

31. The system of claim 18 in which an incursion condition includes a plane on a taxiway intersecting a runway and a plane, vehicle, or other object detected on said runway and said controller subsystem is configured to activate an indicator at the taxiway where it intersects the runway.

32. The system of claim 18 in which said acoustic sensor subsystem is set along one or more select taxiways of the airport.

33. The system of claim 32 in which an incursion condition includes a plane or vehicle on one taxiway and a plane or vehicle on an intersecting taxiway and the controller subsystem is configured to activate an indicator at said taxiway intersection.

34. The system of claim 18 further including a high resolution imager.

35. The system of claim 34 in which the controller subsystem is further configured to activate the high resolution imager in response to an incursion condition.

36. The system of claim 18 further including a radar subsystem.

37. The system of claim 36 in which the radar subsystem includes a millimeter wave or X band radar subsystem.

38. The system of claim 36 in which the controller subsystem is configured to activate the radar subsystem in response to an incursion condition.

39. An airport incursion notification method comprising:

setting along one or more select runways of an airport an acoustic sensor subsystem;

providing indicators located at least at select runway and taxiway intersections;

linking the acoustic sensor subsystem to the indicators; and

activating one or more said indicators if an incursion condition exists as detected by the acoustic sensor subsystem.

40. The method of claim 39 in which a fiber optic cable is buried alongside opposite sides of said one or more runways.

41. The method of claim 39 in which the indicators are configured as above ground warning lights.
