AN/MPQ-53 (PAC-2) The AN/MPQ-53 is the radar program and missile commander for the Patriot MIM-104 defense systems. Specializing in medium/high altitude anti-ballistic missile defense, the system is a collaboration between Lockheed Martin and Raytheon that consists of a C-band frequency.[i] It is a passive electronically scanned array radar system which is remotely operated by 3-4 people using the MSQ-104 Engagement Control Station (ECS) via a cable link.[ii] The MPQ-53 is unique in the sense that it is a “detection-to-kill” system, meaning that a single unit performs all its functions in comparison to other Surface-to-Air Missile Systems (SAM) which require several radars to function efficiently.[iii] The radar can detect and track more than 100 potential targets and has a range of over 100 km.[iv] Being that the MPQ-53 has no moving parts, it makes it difficult to jam and increases its overall success.
AN/MPQ-65 (PAC-3) Under the PAC-3 program the MPQ-53 radar set has been replaced with the MPQ-65. The MPQ-65 is a passive radar meaning it does not emit any signals, but instead collects signals edited from aircraft. This allows the radar to remain undetected as it tracks targets. [v] The upgraded MPQ-65 radar can track up to 100 targets at once. The baseline features are enhanced to better counter developing threats like maneuverable ballistic missiles, stealth cruise missile, and aircraft.[vi] Using a C-band frequency, the radar carries a range of over 100km and is also operated by using the MSP-104 ESC.[vii] The AN/MPQ-65 radar uses a second traveling wave tube (TWT) which allocates more search, detection, and tracking, capabilities than the MPQ-53.[viii]
