The invention discloses an infrared weak and small target background suppression method based on multi-scale rolling guide filtering smoothing. The method comprises the following steps: constructing an image data cube based on a multi-scale RGF for a to-be-processed image; dimension reduction and principal component extraction of an image data cube are carried out on the basis of kernel PCA, abnormal point detection is carried out on the basis of the double-window Mahalanobis distance, infrared weak and small target background suppression based on multi-scale rolling guide filtering smoothingis achieved, and the method has a good suppression effect on the infrared weak and small target background. 本发明公开了一种基于多尺度滚动引导滤波平滑的红外弱小目标背景抑制方法，包括以下步骤：对待处理图像先基于多尺度RGF构造图像数据立方体，再基于核PCA进行图像数据立方体的降维及主成分提取，然后基于双窗马氏距离进行异常点检测，实现基于多尺度滚动引导滤波平滑的红外弱小目标背景抑制，该方法对红外弱小目标背景的抑制效果较好。
