LuTan-1: An Innovative L-band Spaceborne Bistatic Interferometric SAR Mission

Inhalt:
LuTan-1 is an innovative L-Band spaceborne bistatic interferometric SAR mission, aimed at monitoring surface deformations and acquiring highly accurate DEMs. In phase I, two satellites fly in a close helix formation for DEM generation using InSAR. In phase II, two satellites share the common reference orbit with a 180-degree orbital phase difference for differential interferometric applications. Up to now, the first phase of LuTan-1 has successfully completed. In this paper, the processing flowchart along with several results during phase I are demonstrated. In the following lifetime, LuTan-1 will continually provide observation data of high quality for Earth observation.
