The Application of Space Targets Polarization Detection and Recognition

摘要

The disadvantages of traditional optical detection for space targets such as time limitation and serious atmospheric effectare the main restrictions for space targets detection and recognition, especially for GEO satellites. As an opticalparameter, polarization is independent of intensity and spectral, and is sensitive to materials and surface properties.Polarization detection offers distinct advantages in highlighting targets, reducing effect of atmosphere, anddiscriminating camouflage target. Therefore, polarization detection can enhance the detection ability and becomes thehot point of space targets detection. In this paper, the advantages of space targets polarization detection are analyzed, thedevelopment of polarization detection devices and space targets polarization observations are summarized, and the futureof space targets polarization detection is forecasted.
