英文摘要：

According to the corner reflector characteristics with high reflectivity and strong stability,an identification strategy from coarse- to- fine is advanced. Corner reflector is approximately identified by pre- processing; its position accuracy is improved by visual interpretation; and its precise location is extracted through the statistical analysis in spatial and temporal. Cosmo data is used to verify the identification strategy,and the precise location of seven corner reflectors are recognized. Then from theory analysis and experiment result,the identification strategy is very effective.
