摘要
为了增加激光干扰系统对抗光电装备的种类,提出了一种高脉冲能量高重复频率混合型激光干扰方法,并介绍了这种激光干扰方法的核心部分-双光路合成系统的工作原理。在此基础上,分析了双光路合成系统中激光发散角、光束传输距离和岀射面处光斑中心距离等重要参数与远场光束耦合精度的关系。利用ZEMAX软件对双光路合成系统进行了仿真,将理论分析结果与仿真结果进行比较,两者基本吻合,从而验证了这种理论分析方法的可行性。这一结果为双光路合成系统中重要参数值的设置提供了依据。
In order to increase the category of laser irradiation system confronting the electro-optic equipments,a new type laser irradiation method was provided and an introduction of the double beams combination system working principle of the new type laser irradiation method was given.On this base,the relationship between the parameters setting of double beams combination system and effect of combined beams in far field was analyzed.The double beams combination system was emulated by using the software of ZEMAX.The simulating result coincided with theoretical analysis result basically when compared with each other.It proves the feasibility of this analysis method.The results provide some references for parameters setting of double beams combination system.
