The intelligent mine will be the most important weapon system to defend arming helicopter hedgehopping in future war . passive acoustic detection technology is the key technology . with the researching of the national defence pre - researching project which is the research of acoustics compound fuse of anti - helicopter intelligent mine , this paper presents two type of acoustic localization algorithm , emphasizes the discussion of algorithm and presicion of space acoustic localization with sensors at different height in detail and compares them 智能雷弹是防御超低空飞行的武装直升机的重要武器系统，而被动声探测技术是其关键技术，本文结合“十?五”国防预研项目“反直升机智能雷弹声复合引信技术”的研究，对两种空间目标声定位算法进行了深入分析，重点讨论了空间高低阵定位算法，分析了定位精度。
In the later 1980s , more and more technologies and applications for armed helicopters have been developed in western countries , especially the integrated fly / firepower control ( iffc ) of armed helicopters which is key to armed helicopters for promoting the efficiency of battle and for acquiring abilities of aerial warfare 为此,自八十年代后期开始,西方各国都在大力开展有关武装直升机先进技术的应用研究,其中,占核心地位的是武装直升机的综合飞行/火力控制,它是武装直升机能否大幅度提高作战效能,乃至具备空战能力的关键。
Secondly , it come up with the structure and constitute of the giatsa ' s hardware for modern attack helicopter at present time in our country according to the design technics and the development direction of the giatsa home and abroad . it also presented the functions of all the components in the structure and the method to realize it 其次，根据国内外的电子设备地面综合测试系统的设计技术和发展方向，提出现阶段我国现代武装直升机电子设备地面综合测试系统的硬件构成和组成，阐述各组成部件的功能和实现方法。
