Research on Evaluation Index of Anti-Jamming Performance of Guidance System Based on Line-of-Sight Angular Velocity Accuracy
In response to the problem that traditional anti-interference performance evaluation indices are concen-trated at the level of missile guidance systems,which cannot meet the anti-interference performance evaluation of guid-ance systems,based on the analysis of the internal error transmission principle of guidance systems during the anti-in-terference process and the measurement error of guidance systems,this paper proposes a guidance system anti-interfer-ence performance evaluation index based on line of sight angular velocity accuracy,so as to evaluate its anti-interfer-ence 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 cal-culation 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 ac-curacy using recognition time is given.The results of field data testing indicate that the indices can reflect the anti-in-terference performance of missile in different scenarios,and this method has certain rationality.
