摘　　要：提出充分利用导引头提供的信息提高引战配合效率.研究了利用导引头天线测量的视线角速度在弹体的投影进行目标脱靶方向角识别的原理.通过对弹目交会段导弹与目标相对运动关系的分析,得出了识别目标脱靶方向角的数学表达式;针对一种导引头结构设计了可以获得所需识别信息的工程实现方案;给出仿真算例分析脱靶方向角识别的精度.仿真结果表明,识别出的脱靶方向角的精度可以满足引战配合的要求.An approach taking advantage of information assessed from seeker to improve the efficiency in coordination of fuze and warhead is presented. This method for the identification of target miss in azimuth makes use of the projection in missile body coordinate system of line-of-sight rate between the missile and target. Mathematical expression for identifying the target miss in azimuth is inferred by analyzing the relative state of motion of the missile and target in the rendezvous phase. According to a kind of feedback loop of seeker, a project is designed to obtain the needed information on identification. An example is given to analyze the precision in identification of target miss in azimuth. Results of simulation indicate the precision of target miss in azimuth as identified by this method can satisfy the requirements of coordination of the fuze and the warhead.
