Abstract

In this paper, we present a new method for detecting moving dim point targets in image sequences. The algorithm calculates autocorrelation function of projected images including segments of moving target track. The correlation can enhance target intensity and reduce noises. Then, we use Hough transform to determine straight line tracks of targets and to remove false alarm points. The signal-to-noise ratio of images in our experiences is less than 3. Simulation results show that our method can detect the moving targets effectively and is feasible.
