中文摘要: 主动雷达制导是先进防空导弹的主要制导方式之一。主动雷达导引头的作用距离、测角精度、时间常数等决定了末制导精度,但具体影响情况却较难量化,导致制导控制系统指标分解的合理性无法评估。本文提出了一种基于物理模型的制导精度快速评估方法,从建立主动雷达导引头指标描述的数学表征出发,采用数值评估手段,获得比例导引末制导精度影响因素的定量分析准则。数值结果表明,提出的方法可快速得到初始指向误差、导引头测角精度、探测盲距、导弹过载等对制导精度影响的定量化结果,为导弹制导控制系统指标分解提供依据。

Abstract:The active radar homing is employed for air-defense missiles regularly. The guidance accuracy is determined by the detection range, angular accuracy and time constant of active radar seeker. But it is hard to quantitatively analyze the influence which causes that the reasonableness of index decomposition of guidance and control system can not be evaluated. In this paper, a rapid assessment method based on physical modeling is proposed. Firstly, a mathematic description is established. The numerical assessment method is adopted to obtain the quantitative analysis criterion of guidance accuracy with proportion navigation. It shows that the proposed method is well under the quantitative influence result of heading error, angular accuracy of seeker, minimum detection range and the available acceleration. These will be a reference for index decomposition of guidance and control system.
