在电视跟踪制导中,对目标的搜索、匹配和跟踪极易受外界光照条件变化的影响,根据这一特点,文中采用外加人工光照使目标的光照条件发生突变,并从相关跟踪算法出发分析验证了不同光照样式的相关度。目的是从光照样式中得出最佳的干扰模式。通过归一化互相关函数R(u,v)的比较表明利用人工光照使目标的光照突变可以对电视成像制导达到很好的干扰效果。

In TV guidance, target searching, matching and tracking are prone to be affected by external illumination condition. According to this, target illumination mutation was based on artificial lighting, and the correlation of different illumination patterns was analyzed from correlation tracking algorithm perspective. The purpose is to get the best jamming model from all of the illumination patterns. The result indicates using artificial illumination to modulate target image characteristics can largely jam the television-guidance by comparing the crosscorrelation function R(u, v)
