摘　　要：与STT导弹相比,BTT导弹在气动效率、机动能力、控制性能等方面具有明显优势,但其运动耦合特性也给传统研究框架下的制导律设计带来了挑战。本文针对BTT导弹制导律设计问题展开研究,首先描述了BTT导弹制导基本问题,分析了BTT导弹制导律设计的技术难点,需要综合考虑运动耦合、多约束、目标机动、弹体动态效应等因素,然后综述了国内外现代制导律设计的基本方法,将其分为双通道解耦法、球坐标法、现代几何法等,最后指出了BTT导弹制导律的进一步研究方向。BTT（bank-to-turn） missiles have overwhelming advantages than STT（skid-to-turn） missiles in aerodynamic efficiency,maneuverability,controllability,and the like.However,traditional methods of guidance law designing for BTT missiles face many challenges due to its motion coupling characteristic.In this paper the researches in BTT missile guidance law designing were surveyed.In detail,the basic problem for BTT missile guidance was described firstly,and the difficulties in guidance law designing were analyzed,that is,the factors such as motion coupling,multi-constraints,target maneuver,dynamic effects of missile body,and so on,should be considered synthetically.Then the state of the art in BTT missile guidance law designing was discussed,which could be classified as channels decoupling method,sphere coordinate method and modern geometry method.Finally the further directions of BTT missile guidance law were proposed.
