反舰导弹红外成象制导智能跟踪技术研究

THE STUDY OF INTELLIGENT TRACKING TECHNOLOGY FOR IR IMAGING GUIDE ON ANTISHIP MISSILE

成象制导是以高技术为基础的精确制导技术，智能化的成象跟踪是成象制导的一个极其重要的内容。本文提出的成象跟踪方案是以及舰导弹为例而设计的，通过对舰船目标及所处海天背景下的红外图象特征的分析，把整个跟踪过程分为三个阶段，每一阶段分别采用不同的跟踪模式，最后过渡到命中点的选择。并对各跟踪模式进行管理，初步实现了跟踪智能化。把自适应卡尔曼滤波应用于该系统，较好地解决了目标受到遮挡的情况，并通过计算机仿真，达到了预期的目的。

Imaging guide is accurate guide technology based on high tech-nology,the intelligent tracking is an important content of imaging guide. In this paper,the IR imaging tracking scheme is given for antiship missile. By analysing the IR imaging charactersitics of ship and its background,the whole tracking course is divided into three periods,the different tracking mode is taken for every period and the aim point is choised at last.The tracking modes are managed and intelligence is realized preliminarily.An adaptive Karlman filter is used in the sys-tem when target is disturbed or stopped up, and the expected goal is achieved through computer simulation.
