Active Electronically Scanned Array
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled array antenna 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 matrix ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Counter-countermeasure
Electronic counter-countermeasures (ECCM) is a part of electronic warfare which includes a variety of practices which attempt to reduce or eliminate the effect of electronic countermeasures (ECM) on electronic sensors aboard vehicles, ships and aircraft and weapons such as missiles. ECCM is also known as electronic protective measures (EPM), chiefly in Europe. In practice, EPM often means resistance to jamming. A more detailed description defines it as the electronic warfare operations taken by a radar to offset the enemy's countermeasure. History Ever since electronics have been used in battle in an attempt to gain superiority over the enemy, effort has been spent on techniques to reduce the effectiveness of those electronics. More recently, sensors and weapons are being modified to deal with this threat. One of the most common types of ECM is radar jamming or spoofing. This originated with the Royal Air Force's use of what they codenamed ''Window'' during World War II, which A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

AN/TPS-75
The AN/TPS-75 is a transportable passive electronically scanned array air search 3D radar produced in the United States. It was originally designated the TPS-43E2. Although the antenna is a radically new design from the TPS-43, the radar van itself, which houses the transmitter, receiver processors, and displays is very similar to the older TPS-43E2. It is produced in the United States originally by Westinghouse Defense and Electronic Division, which was later purchased by Northrop-Grumman. Description The AN/TPS-75 is the primary transportable Aerospace Control And Warning (AC&W) radar used by the United States Air Force.The US Military description for radar type TPS is "Ground, Transportable; Radar; Detecting, Range and Bearing, Search". The TPS-75 is capable of transmitting 5-Megawatts of power. (Although 5-Megawatts is almost never achieved; realistically it is approx 2.8 Megawatts) This radar was developed as an upgrade of the AN/TPS-43(V), which entered US service in 19 ...

AN/TPS-43
The AN/TPS-43 is a transportable air search 3D radar produced in the United States originally by Westinghouse Defense and Electronic Division, which was later purchased by Northrop-Grumman. It is used primarily for early warning and tactical control, often for control over an associated surface-to-air missile battery or airfield. It is designed to be transported in two M35 cargo trucks and easily air-transportable on two pallets. The TPS-43 uses multiple feed horns and an organ-pipe scanner to rapidly scan its pencil beam vertically while the entire antenna system rotates to scan in azimuth. By comparing the relative power of a return in one or more of the vertical feed horns, the target altitude can be determined. Since its introduction in 1966 it has undergone many modifications. In later versions, the organ-pipe was replaced by a stripline matrix to produce beamforming that had the same output pattern but had no moving parts. Many more upgrades were made to the transmitte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joint Electronics Type Designation System
The Joint Electronics Type Designation System (JETDS), which was previously known as the Joint Army-Navy Nomenclature System (AN System.

TAFLIR
TAFLIR is the abbreviation for the "Tactical Flight Radar" of the Swiss Air Force. TAFLIR is used to improve the Recognized Air Picture and to support air traffic control and air surveillance of the Swiss Air Force. Background The topography of Switzerland is such that certain areas and even radar shadows do not allow surveillance by permanently installed radars placed on mountains. In 1985, five mobile radar systems were purchased for 254 million Swiss francs in order to address this problem. Switzerland procured the mobile radars to improve the nation's aerial warfare capability. However, the system's viability in a military operation was a controversial matter that was brought to attention and addressed in the initial attack waves of the Iraq War. Technology TAFLIR is a version of the AN/TPS-70 radar produced by Westinghouse (now Northrop Grumman), modified for Swiss requirements. It replaced the Target Allocation Radar TPS-1E. These AN/MPQ-64 radars are a variant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 optoelectronic, high-power and high-frequency devices. For example, GaN is the substrate which 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 charac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
