An improved astrometric calibration technique for space debris observation
《Research in Astronomy and Astrophysics》2016年第2期81-88,共8页Rong-Yu Sun Chang-Yin Zhao Yao Lu 
funded by the National Natural Science Foundation of China(Grant Nos.11125315,11403108 and 11273069);the Youth Innovation Promotion Association of CAS(2015252)
An optical survey is the main technique for detecting space debris. Due to the specific character- istics of observation, the pointing errors and tracking errors of the telescope as well as image degradation may be si...

Improved astrometry of space debris with image restoration
《Research in Astronomy and Astrophysics》2014年第8期992-1000,共9页Rong-Yu Sun Chang-Yin Zhao 
funded by the National Natural Science Foundation of China (Grant Nos.11125315 and 11033009)
In order to implement an observing strategy, image degradation that occurs during optical observation of space debris is ineluctable and has distinct characteris- tics. Image restoration is presented as a way to remov...
