摘要 在以往战机空战攻击导引研究中, 仅考虑如何导引载机使之与目标的相对距离达到武器发射射程, 没有同时考虑拦截角度的需求; 或只考虑拦截角而不考虑相对距离的需求。针对这一不足, 本文在深入分析战机攻击导引理论问题的基础上, 创新地用打靶法, 同时考虑追击距离与拦截角度两末端约束, 进行攻击轨迹优化设计。大量仿真研究表明, 所设计的攻击导引方法, 不仅能很好地满足所需的相对距离和拦截角两末端约束, 而且具有较好的可实现性。本研究可为新一代战机导引攻击系统的研制与某型飞机的国产化设计提供参考。 During the past decades, studies on the pursuit-attacking guidance of fighter have drawn much attention, but most of them focused only on single aspect of attack conditions,for example,controling the relative distance between pursuit and evasion fighter to the desired value, determined by on-board missile range. But the other condition, interception angle, is as important as the former for the pursuit to attack the opponent in air combat. Thus, this paper starts the related research to satisfy the later condition. This paper presents a new pursuit method, which is based on the consideration on the two terminal conditions, relative distance and interception angle. First it gives a general outline of the pursuit-attack guidance of fighter, and the mathematical analysis; and the problem can be studied by solving the two-point boundary problem (TPBVP). Then,the shooting method is used to determine the parameters, which actually determine the attack trajectory, to satisfy both the terminal constraints. It should be pointed out that the result is a combination of traditional pure proportional navigation and shooting method, and it not only satisfies both attacking conditions but also is simple to implement.
