In order to solve the problem of infra-red weak target detection in the complex background of sea and air, a detection algorithm based on wavelet maxima is proposed, which calculates all the singular points in the image by calculating the maxima of the wavelet transform module, Modal maxima chain to eliminate complex background such as clouds, sea waves and water antenna and improve the detection ability of single-frame point target.The results show that the algorithm can detect point target with signal to noise ratio of 2
