Space-borne dual-frequency multi-polarization SAR

Inhalt:
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 multipolarization Spaceborne SAR system are compared in detail. Ground experiment system of Dual-frequency multi-polarization Spaceborne SAR and its performance are presented.
