APG-67
The AN/APG-67 is a multi-mode all-digital X band coherent pulse doppler radar originally developed by General Electric for the Northrop F-20 Tigershark program of the early 1980s. It offers a variety of air-to-air, air-to-ground, sea-search and mapping modes, and compatibility with most weapons used by the US Air Force in the 1980s. When the F-20 project ended in the mid-1980s and no other U.S. sales were immediately forthcoming, GE sold off its radar division. It eventually became part of Lockheed Martin, which sells the APG-67 for use on light fighters and trainer aircraft. It has been selected for the AIDC F-CK-1 Ching-kuo of Taiwan, and the Korean FA-50 fighter variant of the T-50 Golden Eagle. Description The APG-67 is a modern radar featuring a planar phased array antenna and simplified electronics housed in three line-replaceable units, one of these being the radar "dish" itself. The entire system weighs less than 160 lb and takes up less than 1.9 cubic feet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northrop F-20 Tigershark
The Northrop F-20 Tigershark (initially F-5G) is a light fighter, designed and built by Northrop Corporation, Northrop. Its development began in 1975 as a further evolution of Northrop's Northrop F-5, F-5E Tiger II, featuring a new engine that greatly improved overall performance, and a modern avionics suite including a powerful and flexible radar. Compared with the F-5E, the F-20 was much faster, gained beyond-visual-range missile, beyond-visual-range air-to-air capability, and had a full suite of air-to-ground modes capable of utilizing most U.S. weapons. With these improved capabilities, the F-20 became competitive with contemporary fighter designs such as the General Dynamics F-16 Fighting Falcon, but was much less expensive to purchase and operate. Much of the F-20's development was carried out under a United States Department of Defense, US Department of Defense (DoD) project called "FX". FX sought to develop fighters that would be capable in combat with the latest Sovie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

AIDC F-CK-1 Ching-kuo
The AIDC F-CK-1 Ching-Kuo (), commonly known as the Indigenous Defense Fighter (IDF), is a multirole combat aircraft named after Chiang Ching-kuo, the late President of the Republic of China. The aircraft made its first flight in 1989. It entered service with Republic of China Air Force (Taiwan) in 1992. All 130 production aircraft were manufactured by 1999. Taiwan initiated the IDF program when the United States refused to sell them F-20 Tigershark and F-16 Fighting Falcon jet fighters following diplomatic pressure from China. Taiwan therefore decided to develop an advanced indigenous jet fighter. The Aerospace Industrial Development Corporation (AIDC), based in Taichung, Taiwan, designed and built the IDF jet fighter. Development Background The preliminary search for a replacement for the ROCAF's F-5s and F-104s began with the XF-6 indigenous fighter project, later renamed ''Ying Yang'', in the late 1970s. After the US established formal relations with China and ended th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northrop F-5
The Northrop F-5 is a family of supersonic light fighter aircraft initially designed as a privately funded project in the late 1950s by Northrop Corporation. There are two main models, the original F-5A and F-5B Freedom Fighter variants and the extensively updated F-5E and F-5F Tiger II variants. The design team wrapped a small, highly aerodynamic fighter around two compact and high-thrust General Electric J85 engines, focusing on performance and a low cost of maintenance. Smaller and simpler than contemporaries such as the McDonnell Douglas F-4 Phantom II, the F-5 cost less to procure and operate, making it a popular export aircraft. Though primarily designed for a day air superiority role, the aircraft is also a capable ground-attack platform. The F-5A entered service in the early 1960s. During the Cold War, over 800 were produced through 1972 for U.S. allies. Though at the time the United States Air Force (USAF) did not have a need for a light fighter, it did procure approx ...

Synthetic Aperture Radar
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. SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam-scanning radars. SAR is typically mounted on a moving platform, such as an aircraft or spacecraft, and has its origins in an advanced form of side looking airborne radar (SLAR). The distance the SAR device travels over a target during the period when the target scene is illuminated creates the large ''synthetic'' antenna aperture (the ''size'' of the antenna). Typically, the larger the aperture, the higher the image resolution will be, regardless of whether the aperture is physical (a large antenna) or synthetic (a moving antenna) – this allows SAR to create high-resolution images with comparatively small physical antennas. For a fixed antenna size and orientation, objects which are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Radars Of The United States
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
F-16 Fighting Falcon
The General Dynamics F-16 Fighting Falcon is a single-engine multirole fighter aircraft originally developed by General Dynamics for the United States Air Force (USAF). Designed as an air superiority day fighter, it evolved into a successful all-weather multirole aircraft. Over 4,600 aircraft have been built since production was approved in 1976. Although no longer being purchased by the U.S. Air Force, improved versions are being built for export customers. In 1993, General Dynamics sold its aircraft manufacturing business to the Lockheed Corporation, which in turn became part of Lockheed Martin after a 1995 merger with Martin Marietta. The Fighting Falcon's key features include a frameless bubble canopy for good visibility, side-mounted control stick to ease control while maneuvering, an ejection seat reclined 30 degrees from vertical to reduce the effect of g-forces on the pilot, and the first use of a relaxed static stability/fly-by-wire flight control system that helps ...

Beyond Visual Range
A beyond-visual-range missile (BVR) is an air-to-air missile (BVRAAM) that is capable of engaging at ranges of or beyond. This range has been achieved using dual pulse rocket motors or booster rocket motor and ramjet sustainer motor. In addition to the range capability, the missile must also be capable of tracking its target at this range or of acquiring the target in flight. Systems in which a mid-course correction is transmitted to the missile have been used. History Early air-to-air missiles used semi-active radar homing guidance, that is the missile used the radiation produced by the launching aircraft to guide it to the target. The latest generation of BVR missiles use a combination of semi-active and active radar. The first such missiles were relatively simple beam riding designs. The Sparrow 1 mounted on the US Navy's Skyknight became the first operational BVR missile in 1954. These primitive BVR missiles were soon replaced by missiles using semi-active radar homing ( ...

AIM-7 Sparrow
The AIM-7 Sparrow (Air Intercept Missile) is an American, medium-range semi-active radar homing air-to-air missile operated by the United States Air Force, United States Navy, and United States Marine Corps, as well as other various air forces and navies. Sparrow and its derivatives were the West's principal beyond visual range (BVR) air-to-air missile from the late 1950s until the 1990s. It remains in service, although it is being phased out in aviation applications in favor of the more advanced AIM-120 AMRAAM. The early Sparrow was intended primarily for use against larger targets, especially bombers and had numerous operational limitations in other uses. Against smaller targets, the need to receive a strong reflected radar signal made achieving lock-on at the missile's effective range difficult. As the launching aircraft's own radar needed to be pointed at the target throughout the engagement, this meant that in fighter-vs-fighter combat, the enemy fighter would often approa ...

AN/APQ-159
The Emerson Electric AN/APQ-159 was an I band/ J band radar designed to upgrade Emerson's simple AN/APQ-153 used in the Northrop F-5. It offered roughly double the range, increased off-boresight tracking angles, and considerably improved reliability. Originally intended to be replaced by the further improved AN/APQ-167, modernized F-5s have typically moved to the entirely new AN/APG-69 instead. Like the earlier APQ-153, the APQ-159 was a purely air-to-air radar system. It had four primary modes of operation, two search modes with different ranges using a simple B-Scope display, a C-Scope gunnery display with ranging and automatic lock-on ("dogfight mode"), and a similar mode used with the AIM-9 Sidewinder that calculated the missile's engagement envelope and provided cues to the pilot to fly into the envelope. The radar offered no air-to-ground modes at all, nor was it capable of firing the AIM-7 Sparrow in spite of its BVR-capable range. The APQ-159's primary upgrade was the a ...

AN/APQ-153
The Emerson Electric AN/APQ-153 was an I band radar system developed for the Northrop F-5E fighter aircraft. Required to fit into the tight confines of the originally radar-less F-5, the system offered relatively simple air-to-air modes and a short detection range. The AN/APQ-157 was a similar system with dual displays and controls for the twin-seat F-5F trainer. Many of the F-5s still flying have been upgraded to the improved AN/APQ-159. The APQ-153 was a relatively simple Pulse-Doppler radar intended to improve gunnery on the F-5. It offered four modes of operation; AA1 and AA2 air-to-air target search at different ranges, "dogfight" which locked onto the closest target and offered ranging and gun cueing, and finally a missile bore-sight cueing mode that calculated the engagement envelope of the AIM-9 Sidewinder and gave the pilot directional cues to help them fly into the envelope. The antenna was necessarily small, a parabolic dish that was stabilized to account for maneu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
