F-117A is first put into combat, stealth aircraft in the previous local wars have played a pioneer role and spiker, destroying a large number of strategic and tactical goals,nike tn, and only one aircraft battle damage itself, show a more high benefit-cost ratio, and F-22 stealth fighter aircraft simulation with three generations of confrontations,barbour catalogue, but also made great exchange ratio, revealing stealth aircraft has become the key to victory in today's Air Force,scarpe hogan outlet online, which is why our country,tiffany outlet, Russia must develop the root cause of stealth aircraft. Data for: Vietnam's S-300 air defense equipment missile radarAs the saying goes,air jordan, there must be a shield spear in the development of stealth aircraft at the same time, countries are also looking for the detection, attack it approaches,hollister italia, including passive detection radar, VHF radars, bistatic radar,air max pas cher femme, and so, in these techniques of the VHF radar is relatively mature.
(Text suspects per capita for the pData for: Vietnam Sourcing Eastern -E meter Active Phased Array RadarSina military Editor: In order to better render military diverse content for readers to meet the reading needs of different readers,tiffany gioielli, to discuss domestic and international strategic developments, military Sina exclusive launch of "deep military" area, depth of interpretation military news hidden behind the trend, three-dimensional rendering China complex environment faced by military strategy,air jordan pas cher, welcomed the attention. 2013 It is reported that Vietnam has purchased East -E radar to Belarus, which have the ability to detect stealth aircraft radar can improve Vietnam's air defense system for stealth target detection capability. Pictures and information from the relevant point of view, the East -E radar should be a UHF phased array radar, the goal is to have some stealth detection capability, but there are low precision,giuseppe zanotti sneakers, low-altitude detection capability poor shortcomings, the overall up talk about Vietnam even purchase the East -E radar, we can not fight our country's F -20 fighter. We know that stealth aircraft has become the main assault force contemporary Air Force, according to the relevant principles of radar, radar target detection range and is proportional to the fourth root of the RCS, RCS declined to say if the target 10 times, then the radar detection range decreased by 50% about 100-fold decline, reduced to about 30% of the original, if reduced to 1,000 times, the radar detection range of 20%, if the team stealth aircraft and interference with the use of airspace with the detection system will further drive down. Since the US invasion of Panama.
economical and reliable way,tn, and even the former Soviet Union and now Russia has been the VHF radar detecting stealth aircraft as an important means. Many other countries are also conducting research VHF active phased array radar. According to the relevant information at home and abroad, the stealth aircraft, mainly through the beam control means modification, to reduce the aircraft RCS to detect the radar main aspects, which include the main edges parallel to avoid large flat, angular, weapon system built, in addition One is the use of stealth coating, it can absorb radar beam irradiation.
which is converted into heat,air jordan pas cher, which reduces the reflection wave, VHF radars But these effects are relatively limited in VHF UHF band wavelength of about 1 about 10 meters, with modern combat aircraft similar size, so no backward scattering direction, increasing the aircraft's RCS,jordan pas cher, when there is exposure to the aircraft surface waves,giuseppe zanotti homme, will have a resonance, to have strengthened the role of the radar echo, This can increase the detection range of the radar. Stealth painted waves in general, I think that we want to achieve better stealth effect,air max pas cher pour femme, stealth coating thickness wave irradiation is proportional to the wavelength of the radar, according to the relevant domestic and international research suggests that this ratio is about radar exposure wavelength of 1 / 10-1 / 3, according to this ratio, if stealth coating has a good effect on the VHF radar, then it needs to reach to a thickness of about 1-3 meters, which for high-speed aircraft or missiles, it is almost impossible to achieve. In addition, there are other advantages VHF radar, such as simple equipment, high reliability, low demand for materials and processes, with some BVR capability, less interference by the waves, as well as the more important point is that it is anti-radiation missiles the ability, the size of the current anti-radiation missiles in the VHF radar wavelengths.
so when VHF radar when exposure to anti-radiation missiles, will resonate, thereby improving VHF radar detection capability for anti-radiation missiles ,tn, and by the elastomer space limitations, passive anti-radiation missile guidance system of modern small receiving antenna, operating frequency 500MHZ or more generally, the work can not be achieved VHF radar 300MHZ, it can not attack VHF radar. Data Figure: Vietnamese air defense forces were equipped with Russian-made S-300PMU2 long-range air defense missile system.Home Design Bureau under the radar data, the East -E UHF active phased array radar for this goal B-52, (the height of 10,000 meters,nike tn 2014, without interference) can reach to 360 km,tn, F-117A stealth attack can be achieved with 350 km, down if there is interference in the case, the detection range of the former reduced to 255 km.
