毫米波宽带相控阵导引头关键技术综述

毫米波宽带相控阵导引头技术是目前世界各国的研究热点。其威慑力决定于它的“快、远、精、多”能力，即快速性、远距探测能力、精度和多目标能力。毫米波宽带相控阵导引头采用电扫描技术，具备快速性；采用毫米波宽带成像技术，能对目标进行准确跟踪拦截，实现精确制导；采用有源阵列天线技术，可以得到较大的合成功率，增加导引头的远距离探测能力；快速灵活的波束控制使得导引头具有检测与跟踪多目标的优势。在分析了毫米波宽带相控阵导引头技术研究现状和基本特点及优势的基础上，主要对有源阵列天线技术、宽带毫米波成像技术、空时自适应处理技术及多目标检测与跟踪技术等毫米波宽带相控阵导引头的关键技术进行了初步探讨。

Review on the Key Technology of MMW Wideband Phased Array Seeker

Now, the research on the MMW wideband phased radar seeker technology is very hot in many countries. The radar seeker’s deterrent force depends on its abilities of agility, long distance detection, precision guidance, and multi-target detecting. The MMW wideband phased radar seeker has agile beam scanning, can tracking the target precisely with the MMW imaging technology; also because of the active phased array, the seeker can get more controlled power to increase the detection distance and tracking multi-targets simultaneously. This paper firstly analyses the research status and the advantages of the MMW wideband phased radar seeker technology, then on the basis of the analysis, mainly in this article the technologies of the active array antenna, the MMW wideband imaging, the space-time adaptive processing, the multi-target detecting and tracking and so on are discussed.
