The Sentinelís mission is to alert and or cue Avenger, the Bradley Linebacker or dismounted Stinger teams of hostile and unknown aircraft, cruise missiles (CMs) and unmanned aerial vehicles (UAVs), protect friendly forces from fratricide and provide air situational data to command and control centers. The Sentinel Radar is the key air surveillance and target acquisition/tracking sensor for short-range air defense (SHORAD) weapons in the division and corps sectors. The Sentinel is accurate, quick-reacting and acquires targets sufficiently beyond the forward line of own troops (FLOT) to reduce SHORAD weapon reaction time and allow engagement at optimum ranges.
The system consists of a state-of-the-art three-dimensional battlefield radar which uses modern phased-array antenna technology, a prime mover with a tactical quiet generator and radios, identification friend or foe (IFF) and interfaces to the forward area air defense (FAAD)command and control (C2) network. The sensor is an advanced three dimensional battlefield X-band air defense phased-array radar with an instrumented range of 40 km. The Sentinel is capable of operating day or night, in adverse weather conditions, in the battlefield environments of dust, smoke, aerosols, and enemy countermeasures. It provides 360 degree azimuth coverage for acquisition and tracking. The Sentinel contributes to the digital battlefield by automatically detecting, tracking, classifying, identifying, and reporting targets, cruise missiles, unmanned aerial vehicles, rotary wing and fixed wing aircraft. Targets can be hovering to fast moving, as well as, from the nap of the earth to the maximum engagement altitude of FAAD weapons. Very accurate and quick reacting, Sentinel acquires targets sufficiently forward of the Forward Line of Own Troops (FLOT) to improve FAAD weapon reaction time and allow engagement at optimum ranges. The Sentinel's integrated IFF reduces the potential for fratricide of Army Aviation and Air Force aircraft. Highly mobile and reliable, the Sentinel's Anti-Radiation Missile and Electronic Counter-Measures resistant performance support Army Corps and Divisional Air Defense operations across the full spectrum of conflict.
