Israel
Israel (; he, יִשְׂרָאֵל, ; ar, إِسْرَائِيل, ), officially the State of Israel ( he, מְדִינַת יִשְׂרָאֵל, label=none, translit=Medīnat Yīsrāʾēl; ), is a country in Western Asia. It is situated on the southeastern shore of the Mediterranean Sea and the northern shore of the Red Sea, and shares borders with Lebanon to the north, Syria to the northeast, Jordan to the east, and Egypt to the southwest. Israel also is bordered by the Palestinian territories of the West Bank and the Gaza Strip to the east and west, respectively. Tel Aviv is the economic and technological center of the country, while its seat of government is in its proclaimed capital of Jerusalem, although Israeli sovereignty over East Jerusalem is unrecognized internationally. The land held by present-day Israel witnessed some of the earliest human occupations outside Africa and was among the earliest known sites of agriculture. It was inhabited by the Canaanites ...

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.

Low Probability Of Intercept
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 inverse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Duty Cycle
A duty cycle or power cycle is the fraction of one period in which a signal or system is active. Duty cycle is commonly expressed as a percentage or a ratio. A period is the time it takes for a signal to complete an on-and-off cycle. As a formula, a duty cycle (%) may be expressed as: :D = \frac \times 100\% Equally, a duty cycle (ratio) may be expressed as: :D = \frac where D is the duty cycle, PW is the pulse width (pulse active time), and T is the total period of the signal. Thus, a 60% duty cycle means the signal is on 60% of the time but off 40% of the time. The "on time" for a 60% duty cycle could be a fraction of a second, a day, or even a week, depending on the length of the period. Duty cycles can be used to describe the percent time of an active signal in an electrical device such as the power switch in a switching power supply or the firing of action potentials by a living system such as a neuron. The duty factor for periodic signal expresses the same notion, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pulse-Doppler Radar
A pulse-Doppler radar is a radar system that determines the range to a target using pulse-timing techniques, and uses the Doppler effect of the returned signal to determine the target object's velocity. It combines the features of pulse radars and continuous-wave radars, which were formerly separate due to the complexity of the electronics. The first operational Pulse Doppler radar was in the CIM-10 Bomarc, an American long range supersonic missile powered by ramjet engines, and which was armed with a W40 nuclear weapon to destroy entire formations of attacking enemy aircraft. Pulse-Doppler systems were first widely used on fighter aircraft starting in the 1960s. Earlier radars had used pulse-timing in order to determine range and the angle of the antenna (or similar means) to determine the bearing. However, this only worked when the radar antenna was not pointed down; in that case the reflection off the ground overwhelmed any returns from other objects. As the ground moves at the ...

Bharat Rakshak
Bharat Rakshak ("Defenders of India") is a website devoted to discussing the Military of India. It was started and is run by military enthusiasts. History Bharat Rakshak was started in April 1997 by bringing together the individual websites of Indian Defence enthusiasts. The website was officially launched on 1 July 1997 by Seetal Patel and Rupak Chattopadhyay. While the concept of Open Source intelligence, as defined by the United States intelligence community, is still evolving in India, Bharat Rakshak has been cited as a website that could be held in the same category as its western counterparts. The forum has many members with experience in Indian Armed Forces and defence technology firms. The site gained some notoriety in December 2007, when it was cited for leaking the Official War Histories written by the Indian Ministry of Defence (MoD) that had remained classified for sometime. Features *An active discussion forum, which has been referred to in the press as a think-tank ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Man Portable Radar
Man-portable radar is a lightweight surveillance radar system that does not require vehicle support to transport or operate. Man-portable radar was developed to introduce radar to remote areas where vehicle support is not feasible. Examples PPE PGSR-3i ‘Beagle’ 'PPE PGSR-3i ‘Beagle’'' is a unique lightweight man-portable radar by 'Pro Patria Electronics'', which is capable of intercepting, detecting and tracking targets moving on or close to the ground. It can also classify and differentiate targets based on their size and movement characteristics. PPE PGSR-3i ‘Beagle’ can operate on standard Bren Tronics military batteries as well as from a vehicle or mains power source. PPE PGSR-3i ‘Beagle’ can scan from 11 to 360 degrees with a continuous 360 degree scanning. PPE PGSR-3i ‘Beagle’ has automatic and manual doppler audio mode, artillery correction mode, continuous 360 degree scanning mode. Has detection ranges of 40 km for very large vehicles 25 km for vehi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
