摘　　要：微型导弹体积小、成本低、精度高,可用于近距离攻击低小慢目标和地面人员车辆,采用捷联可见光导引头制导是比较合理的方案,因此高精度捷联制导信息的提取成为关键。为获取更高精度的制导信息,需要改进提取方法。匹配滤波理论是在考虑传感器不同的动力学特性情况下的一种信息融合方法,依据传感器动态特性进行信息匹配的方法提高制导信息提取精度。首先建立捷联光学成像导引头及其在制导控制系统中的简化模型,依据导引头上各种传感器主要指标,及匹配滤波的原则,推导出相位匹配器。最后,对匹配后的系统提取制导信息,并参与制导系统半实物测试,对比传统惯性滤波器与相位匹配滤波器的效果。结果说明在相位匹配滤波的提取方法获得的视线角速率精度比传统惯性滤波提取方法提高了1倍。For its small bulk,low price and high degree of accuracy,the mini-missile can be used to attack person and vehicle,and the strapdown seeker is a good choice for guidance.The key point is to refine the seeker guidance information.The way of getting guidarne message should be improved.Phase matching filter is a way of intelligence fusion considering the dynamics of different sensor.It increases the accuracy by matching the dynamic of sensor.The guidance and control model of optical imaging strapdown seeker is built firstly,and then the phase matching filter is derived.The giudance information of matched system is extracted at last,and the guidance system using the Hardware-in-loop system is tested.Comparing the matched filtor improved system and the traditional lag compensation sysytem,the line-of-sight rate dloubles.
