AbstractTo meet the needs of detecting GEO(Geosynchronous Orbit)space objects, and prevent the saturation of CCD pixels with long exposure time,a method of stacking series of images with short exposure time is presented.Using the method,the store range of images is enlarged,and the signal to noise ratio(SNR)is promoted,and hence the detection ability of the whole system is improved.The results of experiments demonstrate that the saturation of pixels is eliminated effectively,and the SNR is increased by 3.2 times,and the detection ability is increased by 2.5 magnitude when 10 seriate images are stacked.The location accuracy of stars satisfies the requirement,and using the mean plate parameters for astronomical orientation is reliable.At last the efficiency of the method is proved.
