摘要
在强杂波环境下检测一类重要小目标(如巡航导弹,反舰掠海导弹,隐身飞机)是现代雷达面临的一个最具有挑战性的课题。频率步进雷达,由于其高距离分辨能力及独特的波形和处理,正在用来解决强杂波中小目标的检测问题。文中首先介绍了频率步进宽带高距离分辨雷达的原理和技术,然后讨论了应用频率步进雷达解决强杂波中运动小目标的无杂波区检测和无折叠杂波检测问题。
The detection of an important classe of targets, that is Low radar cross section （ RCS ） targets （ Such as, cruise missiles, Sea skimming anti-ship missiles and stealth aircraft）, embedded in heavy clutter is a challenging problem for modern radar technology. The high range resolution capability of stepping frequency radar with its unique waveform and processing is being exploited to solve the problem of detection of low RCS targets in heavy clutter. The fundamental principle and techniques of stepping frequency wideband high resolution radar are introduced. Then the application of stepping frequency radar to solve the problems of clutter free region detection and of folded clutter-free detection of moving low RCS targets in heavy clutter is discussed in this paper.
