The MIM-104 Patriot is a mobile interceptor missile surface-to-air missile (SAM) system, the primary such system used by the United States Army and several allied states. It is manufactured by the U.S. defense contractor Raytheon and derives its name from the radar component of the weapon system.
Launch of a MIM-104 Patriot missile. The United States Army Integrated Air and Missile Defense [IAMD] Battle Command System (IBCS) is a plug-and-fight network intended to let a radar or any other defensive sensor feed its data to any available weapon—colloquially, "connect any sensor to any shooter".
Another potential disadvantage compared to active radar homing is that the missile must rely on the ground-based radar for guidance, so if the target is able to put an obstacle between itself and the fixed radar system (e.g. a hill), or if it manages to get outside of the radar's tracking envelope (e.g., fly outside of the tracking “fan” of ...
In 1975, the SAM-D missile successfully engaged a drone at the White Sands Missile Range. In 1976, it was renamed the PATRIOT Air Defense Missile System. The MIM-104 Patriot would combine several new technologies, including the phased array radar and track-via-missile guidance. Full-scale development of the system began in 1976 and it was ...
[47] [59] [32] Army doctrine can now be updated to allow the launch of a single Patriot against a single target. [58] [47] By 2021 the Army awarded a $1.4 billion contract to Northrop Grumman for IBCS. [60] Raytheon's new GhostEye radar (previously Lower Tier Air and Missiles Defense Sensor, LTAMDS) [4] replaces the Patriot AN/SPY-65A radar ...
Patriot PAC-3 is a lower-altitude missile and air defense system than THAAD. The AN/TPY-2 is a missile-defense radar that can detect, classify, track and intercept ballistic missiles. It has two operating modes – one to detect ballistic missiles as they rise, and another that can guide interceptors toward a descending warhead.
The THAAD radar and a variant developed as a forward sensor for ICBM missile defense, the Forward-Based X-Band – Transportable (FBX-T) radar, were assigned a common designator, AN/TPY-2, [50] in late 2006/early 2007. The THAAD radar can interoperate with Aegis and Patriot systems, in a 3-layer antimissile defense. [51] [52] [53]
The German Navy and the Royal Dutch Navy have developed the Active Phased Array Radar System (APAR). The MIM-104 Patriot and other ground-based antiaircraft systems use phased array radar for similar benefits. Phased arrays are used in naval sonar, in active (transmit and receive) and passive (receive only) and hull-mounted and towed array sonar
