NMANews2014.11.13---中国无源雷达系统
發佈日期：2014年11月13日 China has claimed its latest passive radar system, the DWL002, will make stealth fighter jets like the United States’ F-22 and Europe’s Neuron identifiable and therefore obsolete. The DWL002 uses paired primary wideband apertures, setting it apart from its predecessors, including Russian-made radars such as the KRTP Tamara series and the ERA Vera-E. Features such as heat-absorbing surface materials, smooth surfaces and hidden engines render stealth fighter jets such as the F-22 undetectable by radars. However, China’s DWL002 passive radar system, which consists of three stations, reads electronic signals emitted by aircraft to detect their presence. The DWL002 passive radar system can detect fighter aircraft within 400 kilometres. For airborne early warning and control aircraft, the radar system can detect them within 600 kilometres. The range of the system means that China would be able to identify aircraft flying over Taiwan and the Senkaku Islands. However, critics have found China’s claims questionable. According to a report by Air Power Australia, the only important breakthrough of DWL002 is the use of paired primary wideband apertures.
中国一直声称其最新的被动雷达系统中，DWL002，将使隐形战斗机如美国的F-22和欧洲的神经元可识别的，所以过时。 该DWL002使用成对的初级宽带小孔，从它的前辈中脱颖而出，其中包括俄制雷达如KRTP塔玛拉系列和ERA维拉-E。 功能，如吸热面材料，光滑的表面和隐藏的引擎渲染隐形战斗机如F-22无法检测到雷达。 然而，中国的DWL002被动雷达系统，它由三个车站，读取由飞机发射，以检测其存在的电子信号。 该DWL002被动雷达系统能够探测400公里中的战斗机。机载预警和控制飞机，雷达系统可以600公里内检测到它们。该系统的范围，意味着中国将能够识别飞机飞越台湾和尖阁列岛。 然而，批评者们发现中国的说法值得商榷。据报告空气动力澳大利亚，DWL002的唯一重要的突破是采用成对的主要宽带小孔。
