Abstract
A weather radar system can be used as an enhanced vision sensor for providing an image on an electronic display during aircraft surface operations. The weather radar sensed image is representative of the external surroundings of the airport surface environment associated with radar returns received by the weather radar system. The radar returns are processed as a collection of radar measurements to determine a high resolution angle and range to a target, using beam sharpening techniques. When the radar image is combined with an image generated from an airport surface database, the combination or comparison of the two independently created images can be used to confirm the integrity of the positioning and attitude source along with the accuracy of the airport surface database.
