YLC-20是一种无源监视雷达系统与被捷克ERA公司发展的VERA-E系统类似。基于“抵达时差原则”,系统在两或三维定位信号源位置通过基于在多传感器信号接收之间“信号差异到达”(TDOA)的多双曲面数学交集求解。使用二个双曲线(三个接收机)系统能获得2D目标位置,当使用最少三个双曲面(四个接收机)系统能达成完整的3D立体目标定位。更高的精度能被使用较多的接收机实现。 VERA-E系统最初发展当做一种电子情报(ELINT)系统用于定位敌人电子传感器。然而,它之后出名是系统能有效地用来发现隐形飞机,传统雷达系统不能够发现。中国在2004年从捷克订购了价值五千五百万美元的六套VERA-E系统,但是交易据传闻由于美国政府的反对被取消。 在2006年4月北京举办的第5届中国国际电子展览会(CIDEX)期间,中国电子科技集团公司(CETC)第14研究所用宣传图片介绍了它的YLC-20无源监视雷达系统,看来与VERA-E相似。无法知道是否YLC-20和VERA-E技术有任何的关联。 附原文供对照参考: YLC-20 TWO-STATION PASSIVE DIRECTION-FINDING AND LOCATING RADAR The YLC-20 is a passive surveillance radar system similar to the VERA-E system developed by ERA of the Czech Republic. Based on the “Time Difference of Arrival Principle”, the system locates the source of signal position in two or three dimensions by solving for the mathematical intersection of multiple hyperbolas based on the Time Difference Of Arrival (TDOA) between the signal reception at multiple sensors. Using two hyperbolas (three receivers) the system can obtain 2D target position, while using at minimum three hyperboloids (four receivers) the system can achieve full 3D target locating. Higher accuracy can be achieved by using more receivers. The VERA-E system was originally developed as an electronic intelligence (ELINT) system for locating enemy electronic sensors. However, it was later noted that the system can be effectively used to detect stealth aircraft, which conventional radar systems are unable to detect. China ordered six VERA-E systems from the Czech Republic worth US$55 million in 2004 but the deal was reportedly cancelled due to the objection of the U.S. government. During the 5th China International Electronic Exhibition (CIDEX) held in Beijing in April 2006, 14th Institute of China Electronic Technology Corporation (CETC) revealed its YLC-20 two-station passive surveillance radar system, which appears to be similar to the VERA-E. It is not known whether the YLC-20 has any connection to the VERA-E technology.
下面是图片中对雷达介绍的文字部分: 图片内容介绍: CETC 中国电子科技集团公司 1、概述。 YLC-20雷达是利用测向和时差定位技术进行目标检测,定位和识别的无源雷达。其主要作战对象包括: A)含有源雷达的空中目标,包括战斗机,空中预警机,无人机等; 2、关键特点。 隐蔽性好:由于系统采用无源体制,自身不对外辐射电磁波,不易被敌方侦察。具有抗ARM能力。 |
