Radar
Radar is a detection system that uses radio waves to determine the distance ('' ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution ...

Euroradar CAPTOR
The Euroradar Captor is a next-generation mechanical multi-mode pulse Doppler radar designed for the Eurofighter Typhoon. Development of Captor led to the Airborne Multirole Solid State Active Array Radar (AMSAR) project which eventually produced the CAESAR (Captor Active Electronically Scanned Array Radar), now known as Captor-E. Development Development started as the ECR-90 at Ferranti's Edinburgh radar labs, home of many British radar systems. The ECR-90 was based on the Blue Vixen radar which had been developed for the BAE Sea Harrier FA2. The selection of the radar had become a major stumbling block in the EFA project, as the Eurofighter Typhoon was known at the time. Britain, Italy and Spain supported the Ferranti-led ECR-90, while West Germany preferred the MSD2000, based on the US AN/APG-65 radar family being developed in a collaboration between Hughes, AEG and GEC. An agreement was reached after the British Defence Secretary Tom King assured his West German counterp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passive Radar
Passive radar systems (also referred to as passive coherent location, passive surveillance systems, and passive covert radar) encompass a class of radar systems that detect and track objects by processing reflections from non-cooperative sources of illumination in the environment, such as commercial broadcast and communications signals. It is a specific case of bistatic radar, the latter also including the exploitation of cooperative and non-cooperative radar transmitters. Introduction Conventional radar systems comprise a colocated transmitter and receiver, which usually share a common antenna to transmit and receive. A pulsed signal is transmitted and the time taken for the pulse to travel to the object and back allows the range of the object to be determined. In a passive radar system, there is no dedicated transmitter. Instead, the receiver uses third-party transmitters in the environment and measures the time difference of arrival between the signal arriving directly fr ...

HEMPAS-CCIAS Radar
The HEMPAS-CCIAS radar is a passive radar developed by five Greek scientists. History In 2006 after studying and planning for six years, the team applied to the Hellenic Army to participate in a research project for the construction and development of the CCIAS system. Simply put this was a network of "passive" radars. Later in 2006 the Ministry of Defense, Chief of General Staff and Chief of Army Staff took part in the project. The Aristotle University of Thessaloniki team made the first presentation of the system to 60 Staff Officers. Immediately after the presentation without any doubt and hesitation, the political and military leadership excited calls for scientists to move quickly. More presentations followed to all sectors of the military. On February 13, 2009 the Council of Defence Planning met and after voting 7-0 in favor of the operational necessity of the system, recommended the urgent consideration of the issue by the Council of Chiefs. The then Chief of Defence Gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low-probability-of-intercept Radar
A low-probability-of-intercept radar (LPIR) is a radar employing measures to avoid detection by passive radar detection equipment (such as a radar warning receiver (RWR), or electronic support receiver) while it is searching for a target or engaged in target tracking. This characteristic is desirable in a radar because it allows finding and tracking an opponent without alerting them to the radar's presence. This also protects the radar installation from anti-radiation missiles (ARMs). LPI measures include: *Power management and high duty cycle, meaning the transmitter is on most of the time (long integration times) *Wide bandwidth (or Ultra-wideband) *Frequency Agility, and frequency selection *Advanced/irregular scan patterns *Coded pulses (coherent detection) *High processing gain *Low sidelobe antennas Rationale Radar systems work by sending out a signal and then listening for its echo off distant objects. Each of these paths, to and from the target, is subject to the inver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thales Nederland
Thales Nederland B.V. (formerly Hollandse Signaalapparaten B.V. or in short Signaal) is a subsidiary of the French multinational company Thales Group based in the Netherlands. The firm was founded as ''NV Hazemeyer's Fabriek van Signaalapparaten'' during 1922 by Hazemeyer and Siemens & Halske to produce naval fire-control systems. During the Second World War, the company's factory was captured and pillaged by the German Army; shortly after the conflict's end, the remaining assets were nationalised by the Dutch government, the company being renamed ''N.V. Hollandsche Signaalapparaten'' (or ''Signaal'' for short). During 1956, the Netherlands-based electronics company Philips became the majority owner of Signaal after buying a large portion of the shares from the government. The firm expanded throughout much the Cold War period, producing various naval electronics and defense systems for a range of customers around the world. During 1990, the French electronics and defence contr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jane's
Jane's Information Group, now styled Janes, is a global open-source intelligence company specialising in military, national security, aerospace and transport topics, whose name derives from British author Fred T. Jane. History Jane's Information Group was founded in 1898 by Fred T. Jane, who had begun sketching ships as an enthusiast naval artist while living in Portsmouth. This gradually developed into an encyclopedic knowledge, culminating in the publishing of ''All the World's Fighting Ships'' (1898). The company then gradually branched out into other areas of military expertise. The books and trade magazines published by the company are often considered the ''de facto'' public source of information on warfare and transportation systems. Based in Greater London for most of its existence, the group was owned by the Thomson Corporation, The Woodbridge Company, then IHS Markit, before being acquired by Montagu Private Equity in 2019.

Incoherent Scatter
Incoherent scattering is a type of scattering phenomenon in physics. The term is most commonly used when referring to the scattering of an electromagnetic wave (usually light or radio frequency) by random fluctuations in a gas of particles (most often electrons). The most well known practical application is known as incoherent scatter radar theory, a ground-based technique for studying the Earth's ionosphere first proposed by Professor William E. Gordon in 1958. A radar beam scattering off electrons in the ionospheric plasma creates an incoherent scatter return. When an electromagnetic wave is transmitted through the atmosphere, each of the electrons in the ionospheric plasma essentially acts as an antenna excited by the incoming wave, and the wave is re-radiated from the electron. Since the electrons are all moving at varying speeds as a result of ionospheric dynamics and random thermal motion, the reflection from each electron is also Doppler shifted. The receiver on the ...
