AIRCRAFT LANDING SYSTEMS AND METHODS

A method for controlling an aircraft 110 includes storing data aboard the aircraft 110. The data include the relative positions of radar targets 114 disposed within a region adjacent to the runway 112. The region is scanned with a radar aboard the aircraft 110 to obtain data corresponding to the relative positions of radar reflections from the region, including reflections from the radar targets 114. The data corresponding to the radar targets 114 is distinguished from the data corresponding to the radar reflections from the region using correlation techniques. The position and attitude of the aircraft 110 relative to the runway 112 is then assessed using the stored data and the data corresponding to the radar targets 114. The position and attitude of the aircraft 110 relative to the runway 112 is also evaluated using an independent navigation system 102, 104. The difference between the assessed position and attitude and the evaluated position and attitude is then used to control the aircraft 110. 本申请公开飞机着陆系统
