摘　　要：为减小激光告警技术中面阵凝视成像探测技术的难度,提出了一种采用柱面透镜作为光学接收系统,利用线阵探测器测定激光辐射源方向的新方法。文中阐述了利用线阵探测器测定激光辐射源方向的原理及基本的结构组成,给出了影响定向方法测量精度的误差因素,并利用codeⅤ光学分析软件对柱面透镜的影响因素进行了定量分析。理论计算结果表明,当采用曲率半径为60mm的柱面透镜作为光学接收系统时,在接收视场不超过10°的前提下,可保证定向精度优于0.3°。In order to reduce the technical difficulty of staring imaging based on two-dimension array detector in laser warning technology,a new method for measuring laser source based on one-dimension array detector using cylinder lens as the optical system was put forward.The principle and the essential configuration layout of this method were expatiated on.The relevant factor of influencing measurement precision was presented.The relevant influencing factor of cylinder lens was analyzed by using code Ⅴ optical analysis software.The academic computational result indicated that the measurement precision excels 0.3° using cylinder lens with 60 mm curvature radius as the optical system when the angle of view of system is less than 10°.
