基于Unity3D视景的机载红外干扰弹仿真系统设计

Simulation System Design for Airborne Infrared Decoy Flare Based on Unity3D

针对机载红外干扰弹对抗训练成本高、风险大、组织实施难的问题,在分析研究红外视景仿真基本原理的基础上,综合运用Unity3D引擎、地理信息系统和计算机仿真技术,构建了面向机载红外干扰弹对抗过程的实时仿真系统。针对4种不同制导类型导引头开展仿真试验,通过分析命中概率、脱靶量、引偏过程等相关过程数据和图像,表明点面结合投放的红外干扰弹使用策略能够较好应对未知体制的导引头,而大面积散布的多点干扰弹是干扰弹可能的发展方向。

Aiming at the problems of high cost,high risk and difficult organization and implementation of airborne infrared jammer countermeasure training,a real-time simulation system for airborne infrared jammer countermeasure process is constructed by comprehensively using Unity3D engine,geographic information system and computer simulation technology on the basis of analyzing and studying the basic principle of infrared visual simulation.Simulation tests for four different guidance types of seeker are carried out.The hit probability,miss distance,deflection process and other related process data and images are analyzed.The test results show that the use strategy of the infrared jammer launched from point to surface can better deal with the seeker of unknown system,and the multi-point jammer scattered in a large area is the possible development direction of the jammer.
