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."

ASR-9 is an airport surveillance radar system admitted into the National Airspace System (NAS), to be utilized by the Federal Aviation Administration to monitor civilian and commercial air traffic within the United States. Developed by Westinghouse, ASR-9 was the first radar system to display air traffic, and weather conditions simultaneously.
The need for a secondary radar system developed from the limitations of primary radar and need for more information by air traffic controllers due to the increasing postwar volume of air traffic. The primary radar displays a "return" indiscriminately from any object in its field of view, and cannot distinguish between aircraft, drones, weather ...

The second advantage of using an ASR-11 is the radar's ability to utilize a pulse sequence diversity. This gives the radar system the capability to limit processing dwells to a small number of pulses. This feature becomes most important when monitoring air traffic is the primary use of the radar.
Mode S transponders are compatible with Mode A and Mode C Secondary Surveillance Radar (SSR) systems. [2] This is the type of transponder that is used for TCAS or ACAS II ( Airborne Collision Avoidance System ) functions, and is required to implement the extended squitter broadcast, one means of participating in ADS-B systems.
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. Westinghouse also built ARSR-4 3-D air surveillance radar in the 1990s for ...
