定向红外对抗系统与技术的发展

红外对抗系统与技术经历了近半个多世纪的发展,先后出现了红外干扰机、红外诱饵及红外烟幕等几类红外干扰技术,并形成了一个庞大的红外干扰器材家族.近年来,随着红外成像寻的制导武器和技术的发展,常规的红外干扰手段对新型红外制导武器的干扰效果越来越不尽人意,人们逐渐提出了以高功率氙灯或激光作为红外能量源的定向红外对抗(DIRCM)概念.该系统具备优越的红外干扰性能,如通过干扰、致眩和毁伤等干扰红外成像导引头、多次重复使用、干扰效率高等,现已成为新一代红外对抗系统的优选方案.回顾了近年来国外新一代定向红外对抗系统和技术的研究发展历程,重点阐述了基于激光的定向红外对抗系统的工作原理、干扰毁伤机理、在技术上的优势及其国外发展现状,预测了定向红外对抗系统与技术的发展趋势.

Development of direct infrared countermeasure system and technology

Infrared countermeasure systems and technology have developed for half a century. Several types of infrared countermeasure systems,such as on-board infrared jamming system, infrared decoy and infrared smoke have appeared, and form a huge family of infrared countermeasure systems. In recent years, with the development of advanced infrared imaging guided weapons and technology, the jamming performance of traditional infrared countermeasure systems became more and more dissatisfactory. The technical concept of direct infrared countermeasure (DIRCM) was gradually proposed, which used high-power Xenon lamp or laser as sources of infrared energy. DIRCM has advantageous infrared countermeasure properties, such as the capability of jamming infrared imaging seeker by jamming, dazzling, in-band damaging and out-ofband damaging, etc, the capability of reuse and high jamming efficiency, which makes it suitable for new generation of infrared countermeasure system. The international research on DIRCM systems and technology in recent years was reviewed. And the operational principle, jamming damage mechanism,technology advantage of DIRCM system and the development status abroad were focused. And the research trends of DIRCM system and technology were forecasted in the next years.
