A new procedure for detecting week and small infrared target in the background clutter was present.Based on the different spatial property between the weak and small infrared targets and the background,the spatial distribution of the infrared radiation of the background clutter was predicted by the double linear interpolation adaptive apatial prediction.By multiscale bubble wavelet transform for the predicting error image,week and smaal infrared target could be detected.Finally,some experimental results for practical infrared sequential images were presented to show the effect of the procedure.
