The AN/FPS-124 is an unattended radar (UAR) providing short range, Doppler radar surveillance of airborne targets. It provides target information to the Regional Operations Control Center (ROCC), and employs built-in-test, performance monitoring/fault isolation and system redundancy enabling it to reconfigure itself when fault detection occurs. The

is designed to provide long-range detection and coverage for drug interdiction support and tactical command and control. Implementation of the North Warning System has resulted in a reduction in Operations and Maintenance (O&M) spending by up to 50% compared to previous systems. Due to extreme northern locations of some of these radars, the physics of radiowave propagation in the 1215–1400 MHz frequency range is even more critical for target detection requirements. The AN/FPS-124 is intended to cover any surveillance gaps left by the North Warning System's long range radar, the AN/FPS-117.
