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 variety of laser interfering systems against optoelectronic equipment, a hybrid laser jamming method with high pulse energy and high repetition rate is proposed and the working principle of the dual optical path synthesis system, the core of this laser jamming method, is introduced. On the basis of this, the relationship between the important parameters such as laser divergence angle, beam transmission distance and spot center distance at the birefringence surface and the coupling accuracy of far-field beam are analyzed. The dual optical synthesis system is simulated by ZEMAX software, and the theoretical analysis results are compared with the simulation results. The two are in good agreement with each other, which verifies the feasibility of this theoretical analysis method. This result provides a basis for the setting of the important parameter values in the dual optical synthesis system.
