Ground Moving Target Indication(GMTI) using spaceborne SAR sensor is a hot topic. Some of growing trends in GMTI are long time monitoring, better detection capability and high resolution imaging of moving targets. To fulfill these conditions, a novel spaceborne dual-channel spotlight SAR experimental mode is designed. The experiments uses Chinese Gaofen-3 SAR satelite. The first experiment is conducted in June 2019 to validate the mode and assess the data. This paper presents preliminary data processing results, include essential preprocess and along-track interferometry (ATI) and displaced phase centre antenna (DPCA) results. The results shows great potential in target detection and high resolution imaging.
