The ASR-11 is an upgraded, advanced version of the previous ASR-9 radar. This next generation radar system has been developed through a joint effort by the Federal Aviation Administration , the Department of Defense and the United States Air Force , who took most of the lead development tasks.
The ASR-11 will replace most ASR-7 and some ASR-8. The military nomenclature for the radar is AN/GPN-30 . The older radars, some up to 20 years old, are being replaced to improve reliability, provide additional weather data, reduce maintenance cost, improve performance, and provide digital data to new digital automation systems for presentation ...
AN/FPN-47 Airport Surveillance Radar (ASR) AN/FPQ-16 Perimeter Acquisition Radar at Cavalier AFS, North Dakota (an engineering development model was tested at Syracuse) AN/FPS-3 search radar; AN/FPS-4 Height-Finder; AN/FPS-5 long Range Search Radar; AN/FPS-6 height finder; AN/FPS-7 Long Range Search Radar; AN/FPS-8 Medium Range Search Radar
Like the ASR-11, CARSR is completely solid state. Westinghouse built ARSR-3. ARSR-3 and 3D search radar were used by the FAA in the Joint Surveillance System (JSS). The radar operated in the L-band at 1250 to 1350 MHz and detected targets at distances beyond 210 nautical miles; 390 kilometres (240 mi). The D model had height-finder capability ...
ASR-9 was the first Radar System to enable the detection of a moving target with circular polarization, therefore significantly enhancing the ability to locate aircraft in various weather conditions. In addition to the enhanced detection system, six separate weather channels can be switched on to display the precipitation reflectivity measured ...
Secondary surveillance radar antenna (flat rectangle, top) mounted on an ASR-9 primary airport surveillance radar antenna (curved rectangle, bottom).. The need to be able to identify aircraft more easily and reliably led to another wartime radar development, the Identification Friend or Foe (IFF) system, which had been created as a means of positively identifying friendly aircraft from unknowns.
An ATC ground station consists of two radar systems and their associated support components. The most prominent component is the PSR. It is also referred to as skin paint radar because it shows not synthetic or alpha-numeric target symbols, but bright (or colored) blips or areas on the radar screen produced by the RF energy reflections from the target's "skin."
