摘要
针对空空导弹的末端制导,提出了一种红外成像与激光测距共孔径的复合导引头光学系统设计方案,可对空中典型目标进行精确探测和跟踪。该系统采用被动红外成像和主动激光测距两种模式进行复合制导,被动红外成像可对目标进行搜索和捕获,主动激光测距可获得精确的弹目距离信息。该复合导引头中被动红外成像与主动激光测距共用一套光学系统,既满足目标搜索和捕获阶段的大探测视场需求,又可以利用精确的弹目距离信息提高导弹比例导引的制导精度。
According to the characteristics of the terminal guidance phase of air-to-air missiles, a scheme of common aperture IR-imagingg/laser-ranging compound seeker optical system is proposed, which can implement precise detection and tracking of typical aerial targets. The seeker design scheme includes two modes ：passive IR imaging mode and active laser ranging model The former is used for target searching and acquisition, and the later is used for obtaining precise missile-target range information. In the compound seeker, the two modes share the common optics system. The compound seeker can not only meet the requirements of the large field-of-view for target searching and acquisition, but also improve the guidance accuracy of the proportional guidance by using the precise range information.
