Abstract

Dual-frequency multi-polarization Spaceborne Synthesis Aperture Radar (SAR) can obtain multi-polarization images of large ground area synchronously. These images include multiple information of the ground target. It benefits target detection, identification, and classification. For high-orbit multi-polarization Spaceborne SAR, it’s difficult to solve the problem of range ambiguity when the look angle is variable. In this paper, ambiguity property of multi-polarization Spaceborne SAR system is analyzed. And Polarization Time Division (PTD), Polarization Frequency Division (PFD), and Polarization Code Division (PCD) characteristics of multi-polarization Spaceborne SAR system are compared in detail. Ground experiment system of Dual-frequency multi-polarization Spaceborne SAR and its performance are presented.
