Polarization Hierarchy and System Operating Architecture for Polarimetric Synthetic Aperture Radar

Abstract

Polarization hierarchy and system operating architecture is one of the key technologies for Polarimetric Synthetic Aperture Radar (PolSAR) system design. In this paper the polarization hierarchies of PolSAR, including Single-Polarization radar, Dual-Polarization radar, Full-Polarization radar, and Compact Polarization radar, are discussed. In addition, the system operating architectures such as Polarization Timedivision multiplexing pulse, Polarization Frequency-division multiplexing pulse, Polarization Code-division multiplexing pulse and Polarization Space-division in Azimuth are presented more in detail.
