What does ASR stand for in aviation radar terminology?

Explanation:
Airport Surveillance Radar is what ASR stands for. This term refers to the ground-based radar system used by air traffic control to monitor aircraft in the vicinity of an airport. It provides position information—usually range and bearing—from the radar site, and often works with secondary radar that interrogates aircraft transponders to identify them and report altitude. Controllers rely on ASR data to safely sequence arrivals and departures and to maintain separation in the terminal area. The other phrases listed aren’t the standard terminology used for ASR in aviation radar.
