摘要 相关检测法是各种红外系统中广泛采用的目标检测方法 ,然而相关检测算法易受到背景和噪声的影响 ,导致匹配虚警较大、定位精度较差等问题。采用光学信息处理中的相位变换方法 ,将红外目标的能量转换成相位形式 ,然后与匹配相关结合来检测目标 ,不仅定位准确 ,而且性能稳健 ,在目标信号很微弱的情况下也能够取得良好的检测效果 ,是一种十分有效的红外目标检测方法。 The correlative algorithm is one of the most popular methods of detecting target in infrared system. However, the performance of the method is influenced by clutter and noise in infrared images. If we transform the grayscale information of inputting infrared images to phase information. The new correlators has sharp correlating peak value. It can detect and position the infrared dimtarget exactly from fluctuating background and strong noise. It's an effective detection algorithm of infrared targets.
