SYSTEMS AND METHODS FOR DETERMINING LOCATION OF AN AIRBORNE VEHICLE USING RADAR IMAGES
First Claim
1. A method for determining a location of an airborne vehicle, the method comprising:
- identifying at least one object in a pre-captured image stored in a memory onboard the airborne vehicle, the identified object defined by a known location;
identifying at least one ground object in a current radar image;
correlating the ground object identified in the current radar image with the object identified in the pre-captured image;
determining relative location between the airborne vehicle and the identified object in the pre-captured image; and
determining the location of the installation vehicle based upon the known location of the identified object in the pre-captured image and the determined relative location.

Abstract
Location systems and methods are operable to determine a location of an airborne vehicle. An exemplary embodiment identifies at least one object in a pre-captured image stored in an onboard memory and defined by a known location, identifies at least one ground object in a current radar image, correlates the ground object identified in the current radar image with the object identified in the pre-captured image, determines relative location between the installation vehicle and the identified object in the pre-captured image, and determines the location of the installation vehicle based upon the known location of the identified object in the pre-captured image and the determined relative location.

14. An airborne vehicle location system comprising:
-
a radar system operable to generate a current radar image based upon radar returns from a ground surface; an onboard memory operable to store at least one pre-captured image; and a processing system operable to; identify at least one object in the pre-captured image, the identified object defined by a known location; identify at least one ground object in the current radar image; correlate the ground object identified in the current radar image with the object identified in the pre-captured image; determine a relative location between the installation vehicle and the identified object in the pre-captured image; and determine the location of the installation vehicle based upon the known location of the identified object in the pre-captured image and the determined relative location. - View Dependent Claims (15, 16)

17. An airborne vehicle location system, comprising:
-
means for receiving radar returns of a ground surface; means for generating a current radar image; and processing means for identifying at least one object in a pre-captured image stored in a memory onboard the airborne vehicle, wherein the identified object is defined by a known location, for identifying at least one ground object in the current radar image, for correlating the ground object identified in the current radar image with the object identified in the pre-captured image, for determining relative location between the installation vehicle and the identified object in the pre-captured image, and for determining the location of the installation vehicle based upon the known location of the identified object in the pre-captured image and the determined relative location. - View Dependent Claims (18, 19, 20)
