【摘要】 从雷达总体设计的角度出发,提出了一系列预警雷达反隐身举措,并做了初步分析。这些举措是短波宽脉冲发射、空间功率合成、多/双基地接收、扇扫合成孔径及脉冲压缩。所有这些举措旨在提高E/N0,并兼容于同一雷达中。更多还原

【Abstract】 The paper deals with a scheme that helps early warning radars detect stealth aircraft far away. The scheme includes techniques such as very low frequency,long pulse duration transmission,RF power from a number of transmitters added together in space coherently and simultaneously,multi / bistatic radar receiving,narrowing beam width in azimuth by scan synthetic aperture techniques as well as pulse duration compression. Those methods mentioned above are all aimed at obviously improving E / N0( the same as signal to noise ratio) which is seriously deteriorated by stealth aircraft. A simple discussion for analyzing compatibility among different system models is also given.更多还原
