AN / MPQ-64
The AN / MPQ-64 "Sentinel" is a short to medium range 3D radar for use in the army's air defense for direct weapons control. It is a pulse Doppler radar operating in the X-band with a phased array antenna .
The radar automatically records, accompanies and identifies the targets. They are divided into hazard classes ( cruise missiles , drones , helicopters and airplanes ), thus optimizing the order of the fight. By using an electronically controlled antenna that works diametrically (in two opposite directions), the same data renewal rate is achieved as if the antenna were virtually rotating at twice the number of revolutions. In the classic version, a range of 40 km is achieved, in the modernized version AN / MPQ-64 / F1, as used by the American forces in Iraq since 2003, 75 km.
The radar is mounted on a single-axle trailer that can be operated unmanned and remotely from the weapon system. Power is supplied by a built-in 400 Hz diesel electric unit. The data lines to the weapon systems consist of broadband fiber optic cable . This data can also be fed into a radar data network.
