采用复合制导的空空导弹,其特点是整个制导过程分为中制导段和末制导段,由于各个制导段采用不同的制导律,存在着不同制导方法间的交接问题,如何完成可靠的交接是复合制导系统所要解决的关键问题之一。文中分析了影响中捷联惯导+红外末制导类型的直升机载复合制导的空空导弹末制导交接段导引头的目标指向偏差问题,分离出影响交接完成的主要因素以为工程研究提供指导。

The compound-guided AAM's whole guidance process can be divided into midcourse guidance and terminal guidance. Because each guidance phase adopts different guidance law, how to complete the smooth handover between the phases becomes a key technique question that the compound guidance system must to face. A statistical method was presented by analysis of the problem that the seeker pointing-angle handover error of the compound guidance AAM for helicopter with SINS+IR terminal guidance. The main factors that affect the handover completed were isolated,there byproviding guidance for engineering study.
