摘　　要：针对传统抗干扰性能评估指标集中在导弹制导系统层面,无法满足导引系统抗干扰性能评估的问题,本文在分析抗干扰过程中制导系统内部误差传递原理的基础上,基于导引系统的测量误差,提出了基于视线角速度精度的导引系统抗干扰性能评估指标,从而在导引系统研制过程中,能够及时对其抗干扰性能进行评估。由于视线角速度精度在外场试验中不易测量,为了提高该指标的测试效率,基于比例导引制导原理,给出了视线角速度精度的简化计算方法,并针对非比例导引制导场景,给出了利用识别时间对视线角速度精度进行等效测试的方法。外场数据测试结果表明,该指标能够反映导弹在不同场景下的抗干扰性能,具有一定合理性。In response to the problem that traditional anti-interference performance evaluation indices are concentrated at the level of missile guidance systems,which cannot meet the anti-interference performance evaluation of guidance systems,based on the analysis of the internal error transmission principle of guidance systems during the anti-interference process and the measurement error of guidance systems,this paper proposes a guidance system anti-interference performance evaluation index based on line of sight angular velocity accuracy,so as to evaluate its anti-interference performance timely in the development process of guidance systems.Due to the difficulty for measurement of the line-of-sight angular velocity accuracy in field experiments,in order to improve the testing efficiency,a simplified calculation method for line-of-sight angular velocity accuracy is proposed based on the principle of proportional guidance.Furthermore,for non proportional guidance scenarios,an equivalent testing method for line-of-sight angular velocity accuracy using recognition time is given.The results of field data testing indicate that the indices can reflect the anti-interference performance of missile in different scenarios,and this method has certain rationality.
