What does ATCRBS stand for in radar systems?

ATCRBS stands for Air Traffic Control Radar Beacon System. This system is used in air traffic control to enhance radar surveillance of aircraft. It operates by using transponders installed in aircraft that respond to interrogations from ground radar systems. When the radar sends out a signal, the transponder on the aircraft replies with information such as its identification and altitude. This exchange allows air traffic controllers to effectively track aircraft, manage airspace, and ensure safe separations between flights. The nomenclature clearly relates to its primary purpose within air traffic control, distinguishing it from options that suggest functions pertinent to target control or automated systems that do not align with established radar terminology in aviation.
