Transceiver
In radio communication, a transceiver is an electronic device which is a combination of a radio ''trans''mitter and a re''ceiver'', hence the name. It can both transmit and receive radio waves using an antenna, for communication purposes. These two related functions are often combined in a single device to reduce manufacturing costs. The term is also used for other devices which can both transmit and receive through a communications channel, such as ''optical transceivers'' which transmit and receive light in optical fiber systems, and ''bus transceivers'' which transmit and receive digital data in computer data buses. Radio transceivers are widely used in wireless devices. One large use is in two-way radios, which are audio transceivers used for bidirectional person-to-person voice communication. Examples are cell phones, which transmit and receive the two sides of a phone conversation using radio waves to a cell tower, cordless phones in which both the phone handset and ...

Zaslon
The Russian (former USSR) BRLS-8B "Zaslon" (Barrier) is an all-weather multimode airborne radar developed between 1975 and 1980 by the Tikhomirov Scientific Research Institute of Instrument Design as part of the weapons control system of the MiG-31 supersonic interceptor. The NATO reporting name for the radar is Flash Dance with the designations "SBI-16", "RP-31", "N007" and "S-800" also being associated with the radar. Description The Zaslon is a pulse-Doppler radar with a passive electronically scanned array (PESA) antenna and digital signal processing. The antenna used by the Zaslon is actually a multi-channel system comprising two separate electronically controlled arrays, an X band radar with 1700 emitters and a L band transponder with 64 emitters brought together into a single antenna. The antenna has a diameter of 1.1 meters and is fixed in position with a scanning sector of ±70 degrees in azimuth and +70/−60 degrees in elevation. The X-band components of the radar uses ...

MiG-31
The Mikoyan MiG-31 (russian: link=no, Микоян МиГ-31; NATO reporting name: Foxhound) is a supersonic interceptor aircraft that was developed for use by the Soviet Air Forces. The aircraft was designed by the Mikoyan design bureau as a replacement for the earlier MiG-25 "Foxbat"; the MiG-31 is based on and shares design elements with the MiG-25. The MiG-31 is among the fastest combat jets in the world. It continues to be operated by the Russian Air Force and the Kazakh Air Force following the end of the Cold War and the collapse of the Soviet Union in 1991. The Russian Defence Ministry expects the MiG-31 to remain in service until 2030 or beyond; that was confirmed in 2020 when an announcement was made to extend the service lifetime from 2,500 to 3,500 hours on the existing airframes. Development Origins The single-seat MiG-25 could achieve high speed, altitude and rate of climb; however, it lacked maneuverability at interception speeds and was difficult to fly a ...

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] |

Shenyang F-8
The Shenyang J-8 (Chinese: 歼-8; NATO reporting name: Finback) is an interceptor aircraft developed by the 601 Institute (Shenyang) in the People's Republic of China (PRC). It was conceived in the early 1960s as a low-risk program based on enlarging the Mikoyan-Gurevich MiG-21F, a version of which the PRC was producing as the Chengdu J-7. The original J-8 experienced protracted development due to disruption from the Cultural Revolution; the prototypes first flew in 1969 but the design was not finalized until 1979 with the aircraft entering service in 1980. The J-8II/J-8B (NATO reporting name: Finback-B) was a major development of the J-8 and was essentially a new aircraft. The J-8II replaced the nose air intake and its shock cone with an ogival radome and lateral air intakes to create room for a modern fire-control radar, and used more powerful engines. The aircraft started development in 1982, and was cleared for production and service in 1988. The J-8II was the basis for all ...

Radar Cross-section
Radar cross-section (RCS), also called radar signature, is a measure of how detectable an object is by radar. A larger RCS indicates that an object is more easily detected. An object reflects a limited amount of radar energy back to the source. The factors that influence this include: *the material with which the target is made; *the size of the target relative to the wavelength of the illuminating radar signal; *the absolute size of the target; *the incident angle (angle at which the radar beam hits a particular portion of the target, which depends upon the shape of the target and its orientation to the radar source); *the reflected angle (angle at which the reflected beam leaves the part of the target hit; it depends upon incident angle); *the polarization of the transmitted and the received radiation with respect to the orientation of the target. While important in detecting targets, strength of emitter and distance are not factors that affect the calculation of an RCS becaus ...
