LuTan-1 is an innovative spaceborne Synthetic Aperture Radar (SAR) mission with bistatic interferometry capability. The mission is composed of a constellation of two identical satellites, each carrying an advanced L-band full-polarimetric SAR. It provides images with spatial resolution down to 3 m and swath up to 400 km. Since the launch in early 2022, two operation modes have been planned to serve the main objectives: bistatic mode for DEM generation and mono-static mode for surface deformation mapping. In this talk, I will provide an overview of the SAR system of LuTan-1, describe the technical challenges occurred during the development such as phase synchronization, range ambiguity and non-linear FM waveform, and present the preliminary LuTan-1 results from the bistatic imaging, DEM generation from bistatic interferometry, deformation mapping from mono-static interferometry and ground target classification from the unique compact polarization.
