中文摘要：

常规俯仰偏航式导引头采用偏航外框架、俯仰内框架的万向支架结构,针对俯仰偏航式导引头因空间结构约束和大框架角盲区的限制而使导引头探测跟踪过程中框架离轴角较小的问题,研究能够同时满足导弹对导引头小型化和大离轴角要求的滚仰式导引头的任务越来越紧迫。滚仰式导引头采用滚转外框架、俯仰内框架的万向支架结构,滚仰式导引头和俯仰偏航式导引头的框架运动形式和跟踪稳定原理存在本质的差异,因此滚仰式导引头的应用还需要进一步研究和分析。通过与俯仰偏航式导引头的对比,分析研究2种导引头的区别和联系,重点从跟踪导弹和目标视线快速滚转以及最大离轴发射角2个方面研究了滚仰式导引头的应用,最后通过数字仿真和分析说明滚仰式导引头的优良性能,表明滚仰式导引头的研究价值和应用前景。

英文摘要：

The gimbal with pitching frame inside the yawing frame is used by conventional pitch-yaw seeker,to tackle the problem of small off-axis Angle in the process of detection and tracking due to the restrictions of spatial structure and constraints of blind area,it is urgent to the roll-pitch seeker to simultaneously meet the requirement of miniaturization and large off-axis. The gimbal with pitching frame inside the rolling frame is used by roll-pitch seeker,which is different to the yaw-pitch seeker,so further research need to be developed to apply it. According to the analysis of differences and relationship between roll-pitch and pitch-yaw seeker,the excellent application performance of roll-pitch on large off-axis angle launch and sharp tracing line of sight rate was presented to illustrate the research value and application prospects of roll-pitch seeker by comparing with pitch-yaw seeker.
