Abstract : The Air Route Surveillance Radar Model 4 (ARSR-4) is a state-of-the-art, three-dimensional, long-range radar. The system is being jointly procured by the Federal Aviation Administration (FAA) and the U.S. military. This radar will replace aging height-finding and long-range two-dimensional air search radars which are currently in use. Forty-four ARSR-4 systems are scheduled for installation around the coastal United States and in Hawaii, Guam, and Guantanamo Bay, Cuba. This report presents the results of the Operational Test and Evaluation (OT&E) of the ARSR-4 radar system. OT&E Integration and Operational tests were conducted in accordance with FAA Order 1810.4B to verify that the ARSR-4 is operationally suitable and effective and can meet operational requirements when integrated into the National Airspace System (NAS). Test results revealed that the ARSR-4 performs most basic functions well. Improved coverage was noted in areas with a history of poor coverage. Results also revealed that the ARSR-4 can process and provide message outputs for a capacity load within the primary coverage area. Controller comments were generally favorable although several problems were identified during testing. The ARSR-4 at Mt. Laguna had a significantly higher beacon split rate than the ARSR-3. The ARSR-4 did not perform reliably during the test period. The number of critical operational problems encountered was excessive. The ARSR-4 did not consistently recover from a short-term power loss. Several power related problems were discovered. Problems were also discovered with the ARSR-4 Built-in Test (BIT) and Fault Isolation Test (FIT) functions and resolution algorithms.
