摘    要:介绍了一种对自然背景下目标进行相关识别的匹配滤波器。由于自然背景的存在,相关点淹没在背景噪声中,使相关器的识别性能迅速下降,甚至完全丧失了识别能力。采用的方法是将包含目标的输入场景及其背景分别编码,然后将背景从输入场景中剔除,只留下目标的频谱成分作为编码信息来制作匹配滤波器,达到抑制噪声、识别目标的目的。

关 键 词:匹配滤波相关识别  频谱  编码

Abstract:The matched filter to recognize the target under natural background was introduced. Because of the existence of background, the correlation peak will be submerged in the output noise, which causes the performance of correlator descended suddenly, even completely lose the ability of recognition. The input scene and the background were encoded respectively, then the background was eliminated from input scene and the spectrum of target that is the true information was used to make matched filter. So the aim of suppressing background noise and recognizing target was gotten.
Keywords:matched filtering correlation recognition  spectrum  encoding
