摘要
当前日益紧张的国际安全形势加速了对陆攻击导弹的发展,红外成像体制的人在回路制导方式在对陆攻击导弹选择、捕获目标过程中占有重要地位。以红外成像对陆攻击导弹为研究对象,针对其末端对目标识别、导引可采取的不同方式,分析了人在回路与自动目标识别的利弊,对人在回路工作过程、优势及存在的问题进行了介绍,重点对人在回路产生的延时误差进行分析,并提出二次近似修正方法,分别以初始导引量和导弹与目标真实距离为变量,使用Matlab进行仿真,得到未修正、一次修正以及使用二次近似修正方法后初始导引量、导弹与目标间真实距离变化对目标误差的影响,通过对比验证,说明此二次延时修正方法的有效性,为提高人在回路导弹制导精度提供了有效方法。
The growing international security situation has accelerated the development of land attack missiles. The infrare dimaging"Man-in-the-Loop"guidance system plays an important role in the process of land attack missile select and captures thetarget. For the infrared imaging land attack missile's different guidance system,analyze the advantages and disadvantages of"Man-in-the-Loop"and ATR. The working process,advantages and existing problems of"Man-in-the-Loop"are introduced.Based on the analysis of the delay error caused by"Man-in-the-Loop",a new model and improving methods for time delay com-pensation of guidance command at terminal guidance are put forward.Through Matlab simulation,with different method the targethorizontal error is influenced and found along with the change of distances and commands.By contrast,the simulation results provethe efficiency of this method.It provides an effective method to improve the guidance precision of"Man-in-the-Loop".
