The AN/TPY-2 is a digital antenna array radar, which operates in the 8.55–10 GHz X band. Raytheon builds it as part of an X-band family, along with the National Missile Defense (NMD) X-Band Radar (XBR) and AN/FPS-129 HAVE STARE. [ 5] The use of X band provides better target resolution than lower frequency bands, for example the L band ...
Ingalls has proposed the San Antonio-class amphibious transport dock as the basis for a ballistic missile defense cruiser with 6.1 m (20 ft) SPY-6. To cut costs, the first 12 SPY-6 sets will have an X-band component based on the existing SPQ-9B rotating radar, to be replaced by a new X-band radar in set 13 that will be more capable against ...
The USAFSS moved to Brooks Air Force Base, in San Antonio, Texas, in April 1949, and then to "Security Hill" at nearby Kelly Air Force Base in August 1953. During the Korean War, the USAFSS personnel provided United Nations Command units with intelligence on the movements of major Korean People's Army forces from Manchuria to Wonsan.
The Air Force ceased using the Lackland AFB radar site on 30 September 1976. [5] [6] [7] The Lackland ADC site was taken over by the FAA (also known as 'San Antonio') and remained in operation for a number of years. This then-FAA long-range radar site was data-tied into the Joint Surveillance System. The site operated the AN/FPS-66A search radar.
Post-World War II radar stations included those of the 1948 "five-station radar net" and the Lashup network completed in 1950, followed by the "Priority Permanent System" with the initial (priority) radar stations completed in 1952 [3]: 223 as a "manual air defense system" [4] with Manual ADCCs (e.g., using Plexiglas plotting boards as at the 1954 Ent Air Force Base command center for ADC.) [3 ...
Number built. 9 – Lockheed Martin 420K. 2 – Lockheed Martin 275K. Map all coordinates using OpenStreetMap. The Tethered Aerostat Radar System ( TARS) [ 2] is an American low-level airborne ground surveillance system that uses aerostats ( moored balloons) as radar platforms. Similar systems include the EL/M-2083 and JLENS.
Synthetic-aperture radar ( SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. [ 1] SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam-scanning radars.
The San Antonio class is a class of amphibious transport docks, also called a "landing platform, dock" (LPD), used by the United States Navy.These warships replace the Austin-class LPDs (including Cleveland and Trenton sub-classes), as well as the Newport-class tank landing ships, the Anchorage-class dock landing ships, and the Charleston-class amphibious cargo ships that have already been ...
