摘　　要：针对光电对抗系统中烟幕无源、激光角度欺骗、激光阻塞、激光压制4种干扰方式,以风标式激光制导炸弹作为对抗目标,建立了激光对风标式激光制导炸弹的光电对抗仿真系统。阐述了系统的仿真流程,重点研究了激光能量大气传输、烟幕透过率、导引头信号处理、干扰效能计算、炸弹控制与运动等数学模型,进行了仿真试验及数据分析。根据仿真结果,分析了各干扰方式的主要影响因素,将影响干扰效果的主要因素分为瞬变型和渐变型两种,并给出二者对干扰效果影响的差异。该系统已应用于某光电对抗内场半实物仿真项目中,为光电对抗武器作战效能的分析与评估提供平台和依据。Electro-optical countermeasures system includes four kinds of interference patterns that are the smokescreen passive, laser angle deception, laser blocking, and laser suppression. Based on these interference patterns, the photoelectric confrontation simulation system is established to confront the weather vane laser-guided bombs. The process of system simulation is described, and the mathematical models of laser propagation, smoke transmission, seeker signal processing, jamming calculation, bomb control and movement modules are mainly investigated, and then simulation experiments and data analysis are performed. According to the simulation results, the main factors that affect the interference effect of various interference manners are analyzed. Furthermore, influencing factors are divided into two types： transient and gradually-varied, and then the characteristics of the influence on interference effects are simultaneously analyzed. In addition, the simulation system has been applied in the semi-physical simulation project, and it can also provide both reference and basis for the analysis and evaluation of the photoelectric confrontation efficiency.
