Clutter Processing of SEEK IGLOO: A Modern Long Range 3-D Radar

摘要

The radar is being developed to replace the outmoded and expensive to maintain AN/FPS-93 and AN/FPS-90 radars now used in Alaska. The AN/FPS-93 is a two-dimensional surveillance radar and the AN/FPS-90 is a two-dimensional height finder radar; both of these older radars have been in operation since the early 1950's. The specification requirements for SEEK IGL00 were set by a combination of the following: (1) performance characteristics of the AN/FPS-90 and AN/FPS-93 radars; (2) performance characteristics of the Semi-Automatic Ground Environment (SAGE) System and the Joint Surveillance System (JSS); (3) sensor requirements using the new generation fighter aircraft; and (4) stringent reliability, maintainability and availability requirements to reduce on-site maintenance and operations personnel. The SEEK IGLOO radar will provide digital output messages (as opposed to the conventional 'blip' signals used with many radar displays) containing range, azimuth and height information for radar and beacon targets.
