Enhanced airport surface surveillance radar

The Federal Aviation Administration (FAA) is installing the third generation of Airport Surface Detection Equipment (ASDE-3) in 35 of the busiest United States airports. This major advancement over existing equipment uses modern radar and display technology to provide ground controllers with a crisp, clutter free display of surface targets, even under conditions of severely limited airport visibility. Modern graphics technology provide flexible traffic situation displays that include airport map overlays on radar data and expanded area windowing capabilities. Recent Research and Development (R&D) enhancements extend the function of ASDE-3 to further aid ground controllers and enhance airport safety. Information from sensors monitoring approaching aircraft, and nonradar sensors reporting aircraft position have been fused to automate potential runway incursion warnings and add aircraft identification tags on traffic situation displays. Significant cost reductions resulting from R&D activities can make it economically feasible to deploy lower cost systems in more airports. This paper describes the design and implementation of ASDE-3, and the improvements that can reduce the burden on controllers, increase airport efficiency, and enhance air travel safety
