摘　　要：对目前应用比较广泛的比例导引法的算法误差进行了深入研究,通过分析飞行器在自导段制导系统的工作原理,建立了基于比例导引原理的导引弹道计算公式,并对二维比例导引问题进行弹道仿真,总结了方法误差与比例导引系数和弹目速度比之间的相互关系。通过与龙格—库塔法相比较发现:本文算法的弹道精度有了进一步的提高。The paper researched on the calculation error of proportional guidance method widely used at present.After analyzing the principle of self-guidance part,the trajectory function was established,and it simulated the two-dimensional problem.Finally it concluded the relationship between proportional guidance quotient and the velocity ratio of aircraft and target.Comparison with the R-K method,the improved algorithm is more accurate.
