中文摘要：

图像匹配技术是目标自动跟踪火控系统中的一个关键技术,介绍了一种基于小波变换的多尺度匹配算法,并将其应用于目标自动跟踪火控系统中。实验表明它通过采用由粗到精的搜索策略,减少了搜索空间,提高了运算速度,具有跟踪精度高、运算速度快和抗噪性强的特点。

英文摘要：

The template match technology is one of key technologies of the target automatic tracking fire control system.In his paper,an effective matching algorithm is proposed based on wavelet multi-sacle analysis.The experiment results prove that the algorithm is faster,more accuate,and higer noise-robust compared with conventional methods.
