摘要
激光塑造大气透镜(laser developed atmospheric lens,LDAL)是一种先进的太空监视概念,即利用高能激光在大气层形成类似于透镜的结构,实现敌方目标的有效监视。介绍这种概念的应用需求,详细分析了“激光塑造大气透镜”的产生机制和系统结构,深入讨论了其面临的技术挑战,包括大气透镜的形成效应、塑造方式、所需激光功率、机载电力、目标监视时间等,并对相关信息进行了分析。分析结果标明:激光塑造大气透镜是一项颠覆性的新兴技术,可能会改变未来的战场感知态势,在实现上需要高功率激光器的小型化、巨大的机载电力、高速摄影、自适应光学以及高精度成像等技术的综合支持。
The laser developed atmospheric lens(LDAL)is an advanced concept of space surveillance,that is,the high-energy laser was used to form a lens-like structure in the atmosphere to achieve the effective surveillance of enemy targets.The application requirements of this concept were introduced,and the generation mechanism and system structure of laser developed atmospheric lens were analyzed in detail.The technical challenges it faces were discussed in depth,which included the formation effect,moulding method,required laser power,airborne power,target surveillance time and so on,and the relevant information was analyzed.The analysis results show that the laser developed atmospheric lens is an overturning emerging technology,which may change the battlefield perception situation in the future.Technologies such as the miniaturization of high-power laser,huge airborne power,high-speed photography,adaptive optics and highprecision imaging are needed for realization.
