Abstract: Paleo-Channels play an important role in reproducing changes of paleo-climate and paleo-ecological environment. The data of polarimetric synthetic aperture radar (SAR) record the backscattering information of ground objects in the form of scattering matrix, which can be used to effectively identify the hidden paleo-channels information. The Western Songnen Plain was taken as the research area, and the Sentinel-1 VV-VH dual-polarization data were selected as the data source. The H/α VV-VH dual polarization mode of Sentinel-1 was decomposed, and a two-dimensional H/α plane composed of scattering entropy H and scattering angle α was constructed. Based on the fact that there is bulk scattering in the paleo-channel filled with sediments and secondary scattering at the bottom interface of the paleo-channel, and the volume scattering power is greater than the secondary scattering, it is confirmed that the paleo-channel scattering type belongs to the multiple scattering of high entropy H/α plane. Combined with the Sentinel-2 image, the paleo-channel information in the study area is finally extracted. The results show that the paleo-channel information without obvious features in the Sentinel-2 image can be extracted by the H/α decomposition in the VV-VH double-polarization mode.

Key words: Songnen Plain, Sentinel-1 data, H/α decomposition, paleo-channels
