一种新型空空导弹红外成像引信

A New Air-Air Missile Imaging IR Fuze

传统的空空导弹引信采用的环视探测方式 ,将引信的信息处理时间限制在极短的范围内 (一般小于 2ms) ,且使引信在某一时刻只能获取变形很大的目标局部图象。这种探测方式对引信探测性能的影响并不大 ,但却严重限制了引信对目标的识别概率。提出了一种新型空空导弹红外成象引信 ,它采用前视红外图象和制导引信一体化技术 ,能够有效地解决上述问题。还分析了该引信的探测距离特性并给出了一些仿真结果 。

It is always side looking for typical air air missile proximity fuzes,so the signal processing time of these fuzes is very short(often<2 ms),and only some distorted partial objects could be included in every frame. Side looking could influence the performance of fuze detecting target little, but could decrease probability of fuze recognizing target very much. In this paper , we propose a new air air missile infrared imaging fuze that can solve the problem of typical fuzes. First, after discussing the principle of this fuze, we analyses its characteristic of detection distance and propose some results of computer simulation. Then, some algorithms of extracting target feature and recognizing target are established.
