An airborne radar system is disclosed. The airborne radar system comprises a radar antenna, radar circuitry coupled to the radar antenna, and a runway database comprising runway location information. The airborne radar system also comprises a processing device retrieving from the runway database, runway location information for a runway being approached by an aircraft, based on the location of the aircraft, and directing a radar beam defined by a polygon which represents the runway and which is derived from the runway information, the processing device determining whether there are any obstacles on the runway.

The airborne sensing system of claim 7, wherein the radar beam is a beam sharpened compressed radar.14. The airborne sensing system of claim 7, wherein the processing device determines the direction of the radar beam based on the location of the polygon.15. A method of detecting an obstacle on a runway, comprising:retrieving location information relating to the location of an aircraft from a location sensor; retrieving, based on the location information, data representative of the location of the runway relative to the aircraft; registering, the runway location using a radar based signal and the data; sensing within the perimeter of the runway location, the presence of an obstacle by directing a beam sharpened radar to scan the area inside a polygon which represents the perimeter of a runway and which is derived from the data. 16. The method of claim 15, further comprising:determining the location of the obstacle within the perimeter of the runway location. 17. The method of claim 15, flirter comprising:communicating the presence of an obstacle to a pilot of the aircraft. 18. The method of claim 15, further comprising:providing an audio alert to the pilot of the aircraft. 19. The method of claim 15,wherein the directing is to a portion of the runway.
