Paper Abstract

The paper put forward a small target trace acquisition algorithm in serial star images of moving background. For the CCD serial star images, while the space target is moving, the background is still moving because of the CCD flat is moving. At the same time, because of dithering of CCD flat and some other reasons, the gray value of target is not invariable, so much as to disappear in the background noise. The algorithm can detect the discontinuous trace of small space target with high accuracy. Originally, the K-sigma cross projection method is used in background star and target area acquisition. Then, a group of N brightest stars in every image is used to estimate the moving vector of the whole background. Finally, a target trace acquisition method is put forward. The simulation experiment is done with two small targets in 16 frame serial star images, and results of trace acquisition show that the algorithm can detect traces of the two targets with high accuracy.
