摘　　要：研究了复杂背景下红外点目标检测的预处理方法。首先给出了红外点目标的场景图像模型，定义了信噪比，然后给出了点目标增强和背景抑制的方法，分别是去图像局部均值和白化处理。最后是预处理的实验结果和方法的性能分析。The preproassing for infrared point targetS detection in complex background, the image model of background and the definition of SNR were presented. Local-average removing and Whitening processing, two method of point target enhancement with background limited were dicussed.The experiment results were analyzed.
