TV制导导弹的导引规律研究

Research on Searching Guidance of TV Guided Missile

TV制导导弹的导引一般可分为导航段、导引段和末制导段三个阶段。该文对不同阶段的导引规律进行了分析,针对导航段传统导引方法与算法的不足,提出了在导航段采用三星定位和惯导组合的制导法,以解决高动态环境下目标捕获、信号跟踪及导航精度的难题。针对TV导引头的瞬时视场较小,射手的反映速度有限,搜索速度不能太高,搜索区域不会很大的特点建立了导引段的先期导引与搜索规律模型。为了提高末制导段的导引精度,减小脱靶量,提出采用追踪法与比例法相结合的复合导引方法,实验仿真结果表明,导引精度得到了很大提高。

The searching phase of TV guided missile is usually divided into three different stages as the navigation, homing and terminal gaidance. In this paper, guidance laws in different phases are analysed. To solve the problem of target acquisition,signal following and navigation precision during the period of navigation, methods of integrated guidance with three geostationary satellites orientation and INS in high dynamic circumstances are put forword. The mathematics models of pre - guiding and searching are established corresponding to the traits of smaller TV seeker instantaneous field ,limited shooter reacting velocity ,low hunting speed and narrow searching area. The compound guidance methods which integrate the tracking and the proportional in terminal phase are raised in order to increase the guiding precision and to decrease the undershoot value. Experiment shows that the guiding precision is raised by a long way.
