Abstract :
Ambiguity is one of the most important factors that influence the quality of SAR images. Although the existing Polarization Time Division (PTD) operation mode of spaceborne polarimetric SAR system can be easily realized, its range ambiguity problem becomes very serious with high-orbit spaceborne sensors. In order to solve this problem, new operation modes based on Polarization Frequency Division (PFD) and Polarization Code Division (PCD) are proposed. The performances of these three modes are compared in detail
