  1. Asc and Dsc are the abbreviations of ascending and descending orbit, respectively, Bp means perpendicular baseline, Inc means incidence angle at scene center, SS beam mode of master and slave data are FBS (fine beam single polarization), DD beam mode of master and slave is FBD (fine bean dual polarization), SD combination between FBS and FBD, U beam mode of master and slave is ultra-fine. Beam mode of JERS-1 SAR is unique
