摘要：	The Airport Surveillance Radar 9 (ASR-9) is a terminal radar that was deployed by the FAA during the early 1990's at more than 130 of the busiest airports in the United States. The ASR-9 Processor Augmentation Card (9PAC), developed at MIT Lincoln Laboratory, is a processor board enhancement for the ASR-9 post-processor. The increased processing speed and memory size of the 9PAC hardware made it possible for new surveillance algorithms to be developed in software in order to provide improved primary radar and beacon surveillance performance. This report describes improvements to the primary radar correlation and interpolation (C&I) process, which is responsible for creating aircraft target reports and filtering out false targets. The 9PAC C&I provides the following improvements: (1) it automates the creation and modification of the road and ground clutter geocensoring process, which had been a time-consuming human-in-the-loop process; (2) it improves the rejection of false targets using multi-layered false target filtering maps; and (3) it improves the detection of general aviation and military aircraft that are not equipped with beacon transponders or have them turned off. The algorithms described in this report have been implemented as part of 9PAC Phase II, which is currently being tested by the FAA at Dallas-Fort Worth, Salt Lake City, Honolulu, Las Vegas, Oakland, Palm Springs, and Sarasota airports. The 9PAC primary radar algorithms function in coordination with beacon processing algorithms which are resident in either the 9PAC for the interim beacon interrogator (IBI) mode of operation or the Mode S sensor for monopulse operation. In the former, the 9PAC performs the functions of radar beacon reinforcement whereas in the latter, the Mode S sensor provides the function.
