飞行器比例导引综述

基于导弹制导和机器人控制等领域，对追踪／截获动目标——导引问题的研究，综观几十年来大量国内外研究成果，系统分析与比较了各种比例导引律的含义、特点与性能。指出纯比例导引及其改进是非常有效的导引方式，可以有效地用于机动目标追踪／截获导引，能为相关领域机动目标导引问题的研究，包括战斗机追踪导引设计提供参考。

An Overview of the Proportional Navigation

Based on the large amount of study on missile navigation-interception laws and robot control, this paper gives an outline of study results of various proportional navigation laws and addresses the definitions, performances and characteristics of the main type of proportional navigation laws. It is mainly point out, by comparative analysis, that the pure proportional navigation,including it's various improved modes, is the most effective navigation-interception law,which can be effectively used to pursuit or intercept the maneuvering targets. It is expected that this survey paper will help readers realize that PPN is the more practical and effective way than GPN and much more attention should be paid on it such as studies on PPN in other fields, including the design of pursuit-attacking guidance systems of a modern fighter.
