Abstract
A method for radar aided positioning of an air vehicle for approach and landing is described. The method includes integrating global navigation satellite system (GNSS) data and inertial data to calculate a position of the air vehicle, scanning the environment forward of the air vehicle with a radar, and accessing a database of terrain features and their radar signatures. The method further includes matching features in the radar scan data to the radar signatures in the database to determine an actual position of the air vehicle and synthesizing glide slope and localizer signals for the approach and landing based on the determined actual position.
