Active Electronically Scanned Array
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled antenna array in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased-array radar (APAR). The AESA is a more advanced, sophisticated, second-generation of the original PESA phased-array technology. PESAs can only emit a single beam of radio waves at a single frequency at a time. The PESA must utilize a Butler matri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radars Of The United States Air Force
Radar is a system that uses radio waves to determine the distance (''ranging''), direction (geometry), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, Marine radar, ships, spacecraft, guided missiles, motor vehicles, map Weather radar, weather formations, and terrain-following radar, terrain. The term ''RADAR'' was coined in 1940 by the United States Navy as an acronym and initialism, acronym for "radio detection and ranging". The term ''radar'' has since entered English and other languages as an wikt:anacronym, anacronym, a common noun, Acronym#All-caps style, losing all capitalization. A radar system consists of a transmitter producing electromagnetic waves in the radio spectrum, radio or microwave domain, a transmitting antenna (radio), antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a radio receiver, receiver an ...

TPY-2
The AN/TPY-2 Surveillance Transportable Radar, also called the Forward Based X-Band Transportable (FBX-T) is a long-range, very high-altitude active digital antenna array X band surveillance radar designed to add a tier to existing missile and air defence systems. It has a range of up to , depending on target/mode. Made by Raytheon, it is the primary radar for the Terminal High Altitude Area Defense (THAAD) missile system, but also cues the AN/MPQ-53 radar of the MIM-104 Patriot system. Patriot PAC-3 is a lower-altitude missile and air defense system than THAAD. In accordance with the Joint Electronics Type Designation System (JETDS), the "''AN/TPY-2''" designation represents the second design of an Army-Navy electronic device for ground transportable surveillance radar system. The JETDS system also now is used to name all Department of Defense electronic systems. The AN/TPY-2 is a missile-defense radar that can detect, classify, track and intercept ballistic missiles.

AN/FPS-117
The AN/FPS-117 is an L-band active electronically scanned array (AESA) 3-dimensional air search radar first produced by GE Aerospace in 1980 and now part of Lockheed Martin. The system offers instrumented detection at ranges on the order of and has a wide variety of interference and clutter rejection systems. The system was originally developed as part of the "Seek Igloo/Seek Frost" effort to replace the older radar systems of the DEW line with designs that could be operated remotely and require much less maintenance as part of DEW's replacement, the American-Canadian North Warning System (NWS). Implementation of the NWS resulted in a reduction in operations and maintenance spending by up to 50% compared to previous systems. GE made a number of modifications to the basic design to better tailor it to different roles. To fill a need for the US Marine Corps, GE developed the transportable AN/TPS-59, and later combined design elements to produce the smaller AN/TPS-77 which is even ...

Republic Of Singapore Air Force
The Republic of Singapore Air Force (RSAF) is the aerial service branch of the Singapore Armed Forces (SAF) responsible for controlling and defending the airspace of the country, and providing air support to the Army and Navy. It was established in 1968 as the Singapore Air Defence Command (SADC) before renaming to its current name in 1975. As one of the larger and more technologically advanced air forces in Southeast Asia, the RSAF has undertaken a significant role in Singapore's military defence strategy since its formation. The RSAF is one of the more modern air forces in the region, with the ability to act as a strong deterrence from potential hostile nations as well as defending the airspace of the country. The RSAF currently has four domestic airbases – Paya Lebar, Changi, Sembawang and Tengah – as well as at the civilian airport of Seletar. The RSAF also has overseas detachments in various countries, most notably in Australia, France, Thailand and the United ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Department Of Defense
The United States Department of Defense (DoD, USDOD, or DOD) is an executive department of the U.S. federal government charged with coordinating and supervising the six U.S. armed services: the Army, Navy, Marines, Air Force, Space Force, the Coast Guard for some purposes, and related functions and agencies. As of November 2022, the department has over 1.4 million active-duty uniformed personnel in the six armed services.

Gallium Nitride
Gallium nitride () is a binary III/ V direct bandgap semiconductor commonly used in blue light-emitting diodes since the 1990s. The compound is a very hard material that has a Wurtzite crystal structure. Its wide band gap of 3.4 eV affords it special properties for applications in optoelectronics, high-power and high-frequency devices. For example, GaN is the substrate that makes violet (405 nm) laser diodes possible, without requiring nonlinear optical frequency doubling. Its sensitivity to ionizing radiation is low (like other group III nitrides), making it a suitable material for solar cell arrays for satellites. Military and space applications could also benefit as devices have shown stability in high-radiation environments. Because GaN transistors can operate at much higher temperatures and work at much higher voltages than gallium arsenide (GaAs) transistors, they make ideal power amplifiers at microwave frequencies. In addition, GaN offers promising c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
