如果说美国在 2 0世纪 6 0年代初研制的“奈基 Ⅲ”反导拦截系统算作是“导弹打导弹”的第一代和在 70年代初研制的“卫兵”反导系统算作是第二代的话 ,那么 ,在此基础上再经过了 3 0年的研制 ,至今出笼的NMD反导拦截系统应属于反导第三代。反导第三代系统又有了新的技术创新并更趋向实用化 ;尤其是在导弹信息的获取系统———GBR雷达的战技性能方面有明显的提高和技术突破。本刊 2 0 0 2年第 3、4期刊出的前两篇文章 (《NMD -GBR地基雷达初样型的技术功能》和《NMDGBR -P雷达信号模拟器的技术功能》)及本篇内容 ,都较全面的反映了未来GBR -N雷达的技术全貌 ,至少是“管中窥豹”。该雷达经过长期的研制 ,无论是在雷达设计指导思想上和研制工作本身都有新颖、独特之处 ,因此说它在NMD全系统中发挥关键作用 ,尤其在雷达进行真假目标识别的关键作战环节中 ,以多普勒频移的成像和距离高分辨率能力来达到此目的 ,可称为有较大的技术突破。
If the “Naiji III” anti-missile interceptor system developed by the United States in the early 1960s is counted as the first generation of “missile-guided missiles” and the “guarded” anti-missile system developed in the early 1970s counted as The second generation of words, then, on this basis, after another 30 years of research and development, the NMD anti-missile interception system that has emerged so far should belong to the third generation of the antimissile. The third generation of antimissile system has a new technological innovation and more practical; especially in the missile information acquisition system --- GBR radar combat technology performance has significantly improved and technological breakthroughs. The first two articles (“Technical Functions of NMD-GBR Ground-based Radar Initial Model” and “Technical Functions of NMDGBR-P Radar Signal Simulator”) published in the 3rd and 4th issues of 2002 (in Chinese) , All reflect the technical picture of the future GBR-N radar in a comprehensive way, at least in the “pipe juxtaposition”. After long-term development, the radar has new and unique features both in the guiding ideology of radar design and in the development itself, and therefore it is said to play a key role in NMD system-wide, especially in the key operations of radar in identifying true and false targets Links to Doppler shift imaging and distance resolution ability to achieve this purpose, can be described as a greater technological breakthrough.
