%X Distributed Spaceborne Interferometric SAR(DSI-SAR) can be explored to implement three possibilities of the coherent combination of SAR images, which are DEM, ocean current imaging and improving resolution in range and azimuth. So the baseline design for DSI-SAR is more complicated than that for INSAR. In this paper, formation flying of small satellites and geometry of DSI-SAR are discussed and the requirements of three SAR coherent combinations for baselines are analyzed. Furthermore, three performance trade-offs in DSI-SAR baseline design are presented. According to these trade-offs, a method to design baseline is given and applied to an L-band DSI-SAR.
