【摘要】 本文以反辐射导弹系统仿真技术为研究重点,论文主要围绕反辐射导弹的关键部件被动雷达导引头以及仿真系统中飞行弹道的建模等问题展开研究,并建立了基于HLA的反辐射导弹分布式仿真系统。为了成功建立反辐射导弹仿真系统,弹道仿真是其中一个关键的步骤,它为总体设计提供重要的性能参数,在总体设计中占有极其重要的地位。所以本文首先建立了结构化的导弹飞行弹道模型,根据弹道导弹动力学特性的不同,分阶段建立了相应的导弹运动学模型,并进行仿真。完成了弹道仿真及其微分方程的数值解法,为反辐射导弹系统的弹道数据分析提供了基础。最后采用捷联去耦模型,建立了反辐射导弹系统中方位与俯仰通道的飞行控制模型,并构建了Simulink模型转换为HLA仿真系统的实时交互模型。文中采用相干视频信号的仿真方法,准确有效的建立了被动雷达导引头目标、噪声以及干扰的数学模型。提出了一种通用的被动雷达导引头系统仿真模型,复现信号通过混频器、AGC和正交解调等一系列处理的变化过程。在信号处理部分,对于被动雷达导引头常用的相位干涉仪测向体制进行了较为深入的分析,构建了被动雷达导引头脉压模型,最终建立了全面合理的信号处理模型。针对于被动雷达导引头仿真系统中数据处理部分,建立了攻击目标过程中需要考虑的各项误差模型,在满足被动雷达导引头所需灵敏度基础上,分析影响被动雷达导引头命中概率的诸多因素,在此基础上,建立了被动雷达导引头攻击运动目标的命中概率模型,为今后被动雷达导引头系统的分析、设计以及作战效果评估等方面提供实验平台。反辐射导弹技术的研究离不开仿真验证系统,在缺乏实际装备的条件下,仿真建模成为唯一有效的途径。为此,本文在最后部分对反辐射导弹对抗建模仿真技术进行了研究,实现了基于HLA标准的由被动雷达导引头、飞行弹道、目标以及三维视景联邦成员组成的分布交互式仿真系统。该系统以MAK RTI和VR-Link为开发环境、依照联邦开发执行过程,开发出了制导系统分布交互式仿真系统的概念模型；建立了联邦的FOM/SOM模型,实现了仿真系统的实时的、逼真的显示。更多还原

【Abstract】 The simulation technology of ARM system is mainly studied, including modeling the PRS which is the key parts of ARM model and ballistic trajectory model.The ARM simulation system based on HLA is built finally.In order to establish the simulation system of ARM, the trajectory simulation is one of the key processes. It provides parameters for overall design and haves important status extremely during the overall design. Trajectory model is setted up after analyzing detailedly. According as dynamics characteristic, relevant sport model of ARM is built and simulated in each phase.In order to provide base for analyzing data of trajectory, solution of differential eguation is completed.It adopts decoupling model to establish the flying control moled of azimuth and pitch channel in the ARM system.The mutual model is proposed which converted simulink model into HLA simulation system.PRS is the key parts of ARM, and its capability to be a direct influence on ARM.The target model, noise model and jamming model are built effectively with the simulation method of video frequency signal. Current simulation model of PRA is proposed. The processing process of signal includes mixer, AGC, limit breadth and demodulation.

In the data processing part, manifold error models are established, and analyses factor of influence hit the target probability. The hit the target probability model is established when the PRS attack athletic target. It can provide experiment platform for PRS system to analyse, devise and evaluate in the future.The research of Anti-radar missiles technology can hardly be accomplished without simulation and validating system. For this problem, when short of actual equipments, simulation and modeling becomes the only effective approach. Therefore, in the last part of this dissertation, the modeling and simulation technologies of Anti-radar missiles are researched, and the advanced distributed simulation protocol-High Level Archtechture (HLA) is applied to the simulation, which is applicable to large and complicated system simulation. Distributed simulation system is made up PRS, trajectory, target and three-dimensional view federation based on HLA. The system adopts MAK RTI and VR-LINK to develop application. According to executive process of federation exploiture, the model of distributed simulation system is exploited, and FOM/SOM modeling of federation is constituted.
