PALSAR splicing data products are combined by the long path of SAR backscatter images observed through JAXA's global basic observation program for PALSAR and PALSAR-2. It is provided in the form of Gamma-0 backscatter, and its geographic coordinate is 0.8 seconds (about 25 meters at the equator). The time interval is annual. The patched data of PALSAR-2 can be used for the period 2015-2021, and the patched data of PALSAR can be used for 2007-2010. Through data filtering, data clipping and other operations, the data of ALOS PALSAR-2 polarized by HH and HV in the middle and upper reaches of the Yangtze River were obtained. It can be used in the research of P-band microwave application.
