摘　　要：针对复杂背景条件下,毫米波导引头目标选择困难的问题,提出了一种基于扫描、相关匹配和波束指向定位的毫米波导引头目标选择方法。首先,毫米波导引头进行两圈扫描,同时记录检测到目标的距离、角度等信息;然后基于一维距离像,对两次检测到的目标进行点体判断,挑选出幅度较大的目标;再将挑选出来的目标进行匹配相关处理;最后,结合火控系统的波束指向,计算相关匹配成功的目标的分布情况,根据最近邻准则实现毫米波导引头的目标选择。试验结果表明,所述方法可有效去除毫米波导引头的虚警,实现感兴趣目标的准确检测,为毫米波制导导弹的精确打击和高效毁伤提供坚实的基础。Aiming at the difficulty in target selection of millimeter wave(MMW) seeker under complex scenes,a target selection method of millimeter wave seeker based on scanning, relational matching and beam pointing position is presented. In the beginning, the millimeter wave seeker implements two rounds of scene scanning, and records the useful information of range and angles associated with the target. And based on the one-dimensional range image, the point and the body of the detected target are conducted twice, and the target with larger amplitude is selected, then, the selected target is processed with match correlation;Finally,combining with the beam pointing of the fire control system, the distribution of targets with successful relational matching is calculated, and the target selection of millimeter wave seeker is realized according to the nearest neighbor criterion.The experimental results show that the proposed method can effectively remove the false alarm of the millimeter wave seeker, realize the accurate detection of the target, and provide a solid foundation for the precise strike and efficient damage of the millimeter wave guided missile.
