In the modern defense system, the value is high.Ĭhina has developed an advanced compact size maritime radar which can maintain constant surveillance over an area of the size of India, media reported on 09 January 2019. A radar is equivalent to dozens of traditional system radars, especially its ability to exceed the line of sight and anti-stealth. Compared with traditional radar, HF ground wave radar has a long detection range and a wide coverage. This radar is said to have successfully detected stealth targets. The winning project is the domestic high-frequency ground wave detection radar. On 09 January 2019, China's famous radar expert, professor of Harbin Institute of Technology, and academician of the two academies Liu Yongtan won the 2018 National Supreme Science and Technology Award.
67th Element near Wenlin City Shitang Village.
66th Element near Jinjiang, Fujian province Sanshan Village and.61st Element based near Xitangqiao Village.Two are near Xiangfan: the 52nd Element in the Zaoyang Municipal District and the 53rd in Nanzhang County. The PLAAF radar brigade has at least six subordinate elements (fendui). A guarded underground facility, to the east of the village, could house the OTH surveillance and warning system. The PLAAF “Skywave Brigade" is situated in the southern edge of Xiangfan, Hubei province, or specifically in Yingpan Village in the Xiangcheng District. Transmitter beaming direction is determined by measuring TX LPAA pointing direction at each TX site and except for site 2 with only 1 transmitting direction (60 degrees coverage sector), the coverage for rest of the sites are a comination of 2x adjacent 60-degree sectors (120 degrees) which result from the use of 2 independant LPAA at the transmitter site.Ī relatively new PLA Air Force radar brigade – the 95980 Unit – operates the OTH radar system. Normally, all the Chinese OTH-SW radars will be up at the same time using different frequencies, and their OTH-B radars will be operating simultaneously. The earliest imagery depicting one of these systems was captured in 2003, suggesting that the array has been a relatively recent deployment. From this point of view, the two are complementary to each other and constitute an important part of China's surveillance of the sea's visual line of sight.
The high-frequency ground wave over-the-horizon radar with a distance of hundreds of kilometers is the first choice for covering this area. On the contrary, due to the nature of the sky-wave over-the-horizon radar, there must be a short-range blind zone of hundreds of kilometers, which makes it impossible to form effective coverage of the coastal area. The relatively shorter range does not mean that the high-frequency ground-wave over-the-horizon radar is not as important as the sky-wave over-the-horizon radar. This is the only transmitter antenna configuration in the radar network, only one LPAĬonstruction took place in 2014 to relocate the Control and RX sites that are close to a nearby developing industrial park.
