人在回路对导弹制导性能的影响研究

摘要

为了研究人在回路制导方式对导引头控制系统及对比例导引和弹道成型等典型末制导回路的影响,本文在固有射手模型的基础上建立了数字传输人在回路导引头模型,对比分析了自寻的模式、光纤传输人在回路和无线电数字传输人在回路导引头模型的特性;基于无线电数据传输的人在回路模式必然存在的较大的数据传输延时环节,对比研究了不同数据传输延时对导引头控制系统稳定性和快速性的影响.将自寻的导引头模型、光纤传输人在回路导引头模型和无线电数字传输导引头模型分别引入比例导引及弹道成型制导回路中,对比分析了三种模型对制导回路脱靶量的影响;在此基础上分析了延时500 ms时在延时和角度约束条件的脱靶量变化规律及最小末制导时间分布特点,进一步在特定任务下分析了其对导弹飞行过程中过载变化及探测器误差的影响,探讨了人在回路制导模式在比例导引及弹道成型制导律中的可行性.%To study the effects of soldier-in-the-loop(SIL)on the typical guidance loop such as pro-portional navigation(PN)law and trajectory shaping guidance(TSG)law,SIL seeker model is estab-lished based on inherent soldier model,and the characteristics of homing mode,fiber optic transmission SIL and radio digital transmission SIL seeker models are compared.Because of the large delay of SIL with radio digital transmission,the influences of data transmission delay on stability and fast of seeker control system with different models are researcched.By introducing these three models into the proportional navi-gation and trajectory shaping guidance loop,the influences on guidance loop miss distance are analyzed.Based on the simulation of guidance loop with proportional navigation law and trajectory shaping guidance law,the variation of miss distance and the distribution of the minimum terminal guidance time in time de-lay and angle constraint conditions are analyzed when time delay is 500 ms.Under the condition of typical air-to-ground missile,the influences on overload and detector error are analyzed,and the feasibility of SIL guidance mode in proportional navigation law and trajectory shaping guidance law is discussed.
