英文摘要	To improve the detection precision of a geostationary satellite orbit determination system, a target recognition method based on local region multi-feature correlation was proposed by analyzing the characteristics of a star image taken by a drift-scan CCD. A morphological filter method was used to suppress the background of star image and eliminate its non-uniformity. After homogenizing the image background, the correlation coefficients of three features (pixel values, contrast ratios and linear correlation) in local region were analyzed. On the basis of correlation coefficients, the optimal threshold was determinect to isolate the pixels of the satellites and the background stars and ultimately to identify the pixels of the satellite targets. The star images of geostationary satellite were processed, the experimental results show that this method removes the influence of background stars on target recognition, decreases error detection rate and accurately detects geostationary satellite targets. It can fulfill the requirement of reliability, stabilization and accuracy of geostationary satellite orbit determination. 2015, Chinese Academy of Sciences. All right reserved.
