摘要
该文介绍了激光引信系统全数字仿真的基本方法及系统的主要组成,详细探讨了仿真系统中目标模型、激光反射模型、引信模型等关键环节的建模方法,并基于可视化和OPENGL技术,建立了一套实用的针对激光引信的通用全数字仿真系统,用于各种激光引信的目标探测、启动点分析、引战配合效果评估等。该系统采用平面面元拟合目标三维表面,并以表面材料BRDF与目标LRCS的关系作为激光反射特性计算的基础,通过面元合成计算近场复杂目标的激光反射功率,具有计算过程简单、仿真精度高的特点,更适合于工程的应用。
In this paper, the basic simulation method and main frame for fuze system digital simulation were intruduced first. And then, the modeling technique such as target model, laser scatter model, fuze model and so on were lucubrated. Furthermore, by using visualization and OPENGL technique, a general digital simulation software for laser fuze was developed on PC. It can be used in target detection simulation, actuation characteristic analysis, fuzewarhead coordination evaluation etc. In this system, target 3 -D model was built by using plane elements surface fitting method,and based on the relationship between LRCS and BRDF of surface material ,the total laser scatter power from near-field complex target was calculated by synthesizing all the element results. This system is more fit for the engineering applications for its simple calculation process and high simulation precision.
