Paper Abstract

The goal of this study is to examine the potential of deriving information comparable to quad-polarization synthetic aperture radar (SAR) data from dual-polarization data. Multi-polarization data have shown the potential to increase further the ability of extracting physical quantities of observation targets. Above all, quad-polarization data have more information than others, but they are relatively few in number compared with single or dual-polarization data. Although there are many SAR systems capable of quad-polarization observation, most of them are operated mainly on single or dual-polarization mode because of limited data transfer rate, area of coverage, required resolution, other system restriction, and so on. Thus, there is a certain trade- off between data availability and multi polarization. Therefore, we focused on dual-polarization as a good compromise between single and quad-polarization data. In this study, we investigated possible alternative parameters that can be derived from HH-VV dual-polarization data and can serve as substitutes for cross-polarization component in quad-polarization data. Experiments are performed using the Advanced Land Observation Satellite-Phased Array L-band SAR (ALOS-PALSAR) quad-polarization data. The cross polarization component in the data is used as benchmark for the alternative parameters.
