F-117A、B-2等隐身战斗机、轰炸机的出现和在局部战争中成功的使用,使反隐身技术引起丁广泛的重视,竞相研究和发展,将隐身技术与反隐身技术的斗争推向一个新的阶段。目前,从探测飞机的手段来看,雷达探测约占60％,红外探测约占30％,可见光和其他探测手段占10％左右。下面介绍一些可能采川的反隐身技术措施。 1.增大雷达发射功率可提高雷达的作用距离,主要技术途径有功率合成技术。有源相控阵雷达就是典型的功率合成雷达。 2.提高天线增益,降低噪声系数这也能增大
The emergence of stealth fighters such as F-117A and B-2, and the successful use of bomber planes in the local wars have caused anti-stealth technology to attract a great deal of attention, compete for research and development, and push the fight between stealth technology and anti-stealth technology to one New stage. At present, from the means of detecting aircraft, radar detection accounts for about 60%, infrared detection accounts for about 30% and visible light and other detection methods account for about 10%. Here are some of the possible anti-stealth technology measures. 1. Increase the radar transmitting power can increase the range of radar, the main technical ways are power synthesis technology. Active phased array radar is a typical power synthesis radar. 2. Increase antenna gain, reduce noise figure This can also be increased
