|
摘要
随着第四代红外成像空空导弹的发展,在制导半实物仿真过程中导引头对红外图像仿真的需求逐步提高,本文在已有基于导引头光轴指向的变跟踪点红外场景仿真建模技术研究的基础上,对变中心点红外场景仿真建模在分布式制导半实物仿真系统中引入的时间误差进行分析。在充分考虑可能引入时间误差的各参数的可能取值及噪声情况后,给出了定量的时间延迟结果,分析了各参数对时间延迟的贡献,为变跟踪点红外场景仿真技术的工程应用提供数据与理论依据。
With the development of the fourth-generation IR imaging air-to-air missile,the requirement of seeker for image simulation is increased gradually in the process of guidance hardware-in-the-loop simulation. On the basis of existing research on infrared scene simulation modeling technology of variable tracking point based on seeker optical axis pointing,in the paper by the IR scene simulation modeling of variable center point,the time error introduced in the distributed guidance hardware-in-the-loop simulation system is analyzed. After fully considering the possible values and noise conditions of various parameters that may introduce time errors,quantitative time delay results are given,and the contribution of various parameters to time delay is analyzed,which provides data and theoretical basis for the engineering application of variable tracking point infrared scene simulation technology.
