| Country of origin | United States |
|---|---|
| Introduced | Late 1970s |
| Type | Short-range radar system |

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.[1]
The AN/FPS-117 and AN/FPS-124 form an array of radars stretching across North America from Alaska, United States to Labrador, Canada. This North Warning System 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.
Classification of radar systems
[edit]Under the Joint Electronics Type Designation System (JETDS), all U.S. military radar and tracking systems are assigned a unique identifying alphanumeric designation. The letters “AN” (for Army-Navy) are placed ahead of a three-letter code.[2]
- The first letter of the three-letter code denotes the type of platform hosting the electronic device, where A=Aircraft, F=Fixed (land-based), S=Ship-mounted, and T=Ground transportable.
- The second letter indicates the type of equipment, where P=Radar (pulsed), Q=Sonar, and R=Radio.
- The third letter indicates the function or purpose of the device, where G=Fire control, R=Receiving, S=Search, and T=Transmitting.
Thus, the AN/FPS-124 represents the 124th design of an Army-Navy “Fixed, Radar, Search” electronic device.[2][3]
