WThe AN/APG-68 radar is a long range Pulse-doppler radar designed by Westinghouse to replace AN/APG-66 radar in the F-16 Fighting Falcon. The AN/APG-68(V)8 and earlier radar system consists of the following line-replaceable units:Antenna Dual Mode Transmitter (DMT) Modular Low-power radio frequency (MLPRF) Programmable signal processor (PSP)
WThe AN/FPS-17 was a ground-based fixed-beam radar system that was installed at three locations worldwide, including Pirinçlik Air Base in south-eastern Turkey, Laredo, Texas and Shemya Island, Alaska.
WThe AN/SPN-46(V)1 is a Precision Approach and Landing System, manufactured in the United States, by Textron Systems, which is used on aircraft carriers of the United States Navy. The radar uses two dual-band radar antennas, which also function as transmitters, to guide planes or helicopters to the ship.
WThe AN/SPY-1 is a United States Navy 3D radar system manufactured by Lockheed Martin. The array is a passive electronically scanned system and is a key component of the Aegis Combat System. The system is computer controlled, using four complementary antennas to provide 360 degree coverage. The system was first installed in 1973 on USS Norton Sound and entered active service in 1983 as the SPY-1A on USS Ticonderoga. The -1A was installed on ships up to CG-58, with the -1B upgrade first installed on USS Princeton in 1986. The upgraded -1B(V) was retrofitted to existing ships from CG-59 up to the last, USS Port Royal.
WThe AMDR is an active electronically scanned array air and missile defense active electronically scanned array 3D radar under development for the United States Navy (USN). It will provide integrated air and missile defense, and even periscope detection, for the Flight III Arleigh Burke-class destroyers; variants are under development for retrofitting Burke Flight IIA, and installation aboard FFG(X), Ford-class aircraft carriers and San Antonio-class LPDs.
WThe AN/SPQ-11 Cobra Judy was a PESA radar found on the USNS Observation Island (T-AGM-23) missile range instrumentation ship.
WUSNS Howard O. Lorenzen (T-AGM-25) is a Missile Range Instrumentation Ship built for the U.S. Navy by VT Halter Marine of Pascagoula, Mississippi. The keel was laid during a ceremony on August 13, 2008, and the vessel became operational in 2014. This ship carries a next-generation active electronically scanned array radar system named Cobra King.
WCobra Mist was the codename for an Anglo-American experimental over-the-horizon radar station at Orford Ness, Suffolk, England. It was known technically as AN/FPS-95 and sometimes referred to as System 441a; a reference to the project as a whole.
WThe CXAM radar system was the first production radar system deployed on United States Navy ships, operating in the mid-high VHF frequency band of 200 MHz. It followed several earlier prototype systems, such as the NRL radar installed in April 1937 on the destroyer Leary; its successor, the XAF, installed in December 1938 on the battleship New York; and the first RCA-designed system, the CXZ, installed in December 1938 or January 1939 on the battleship Texas. Based on testing in January 1939, where the XAF was more reliable, the US Navy ordered RCA to build six XAF-based units for deployment and then shortly thereafter ordered 14 more.
WH2X, officially known as the AN/APS-15, was an American ground scanning radar system used for blind bombing during World War II. It was a development of the British H2S radar, the first ground mapping radar to be used in combat. It was also known as the "Mickey set" and "BTO" for "bombing through the overcast" radar.
WThe Joint Surveillance System (JSS) is a joint United States Air Force and Federal Aviation Administration system for the atmospheric air defense of North America. It replaced the Semi Automatic Ground Environment (SAGE) system in 1983.
WMcDowell Grove Forest Preserve, located in Naperville, state of Illinois, is a 439-acre (178 ha) preserve on the West Branch of the DuPage River.
WThe Multi-role Electronically Scanned Array (MESA) is a surveillance radar system for the Boeing 737 AEW&C airborne early warning and control aircraft. The radar is produced by Northrop Grumman.
WThe Hughes SCANFAR was the first phased array radar system to be deployed by the US Navy, installed on the USS Long Beach (CGN-9) and USS Enterprise (CVN-65). It consisted of two search radars, the AN/SPS-32 and the AN/SPS-33. In 1982, the system was removed from Long Beach, and was replaced by the AN/SPS-48 during a comprehensive overhaul. Aboard the Long Beach, the system used AN/SPG-55 radars for missile guidance.
WThe SCR-268 was the United States Army's first radar system. Introduced in 1940, it was developed to provide accurate aiming information for antiaircraft artillery and was also used for gun laying systems and directing searchlights against aircraft. The radar was widely utilized by both Army and Marine Corps air defense and early warning units during World War II. By the end of World War II the system was already considered out of date, having been replaced by the much smaller and more accurate SCR-584 microwave-based system.
WThe SCR-270 was one of the first operational early-warning radars. It was the U.S. Army's primary long-distance radar throughout World War II and was deployed around the world. Its also known as the Pearl Harbor Radar, since it was an SCR-270 set that detected the incoming raid about 45 minutes before the December 7, 1941, attack on Pearl Harbor commenced.
WThe SCR-584 was an automatic-tracking microwave radar developed by the MIT Radiation Laboratory during World War II. It was one of the most advanced ground-based radars of its era, and became one of the primary gun laying radars used worldwide well into the 1950s. A trailer-mounted mobile version was the SCR-784.
WThe SCR-658 radar is a radio direction finding set introduced by the U. S. Army in 1944, was developed in conjunction with the SCR-268 radar. It was preceded by the SCR-258. Its primary purpose was to track weather balloons. Prior to this it was only possible to track weather balloons with a theodolite, causing difficulty with visual tracking in poor weather conditions. The set is small enough to be portable and carried in a Ben Hur trailer.
WThe SCR-784 was a radar set used by the U.S. Army designed to be an amphibious version of the SCR-584, to control the fire of anti-aircraft batteries, and mounted on a searchlight trailer called a K-84. The set was used to guide the flare plane over the target.
WSJ radar was a type of S band (10-cm) radar set used on American submarines during the Second World War. The widespread use of the SJ radar, combined with the very low use of radar in the Imperial Japanese Navy gave great operational flexibility to the United States Navy's submarine campaign in the Pacific Ocean.
WThe VT-158, also known as the Zahl tube, was a vacuum tube invented by American physicist Harold A. Zahl in the 1930s and used during World War II and the Korean War. It allowed the radar technology at the time to detect low-flying planes by generating enough power to produce ultrahigh frequency energy.
