According to the frequency characteristic of nature background and small target  a method of detecting targets based on wavelet energy is suggested. The energy of targets in horizontal and vertical direction outclass that of background  or we can say  the gray degree of targets outclass that of background. Then through selecting adaptive region-value  targets and background can be divided. By the method of classifying  the figure centers of every target can be calculated. According to the figure centers of every target in several neighboring frames  the position and velocity of every target in next frame can be estimated by Kalman filter. Experiment results have shown that small targets in sea or sky nature background can be detected by this method  and they can be tracking.
