We analyse the systematic model and working principle of distributed satellites SAR system based on three-dimensional reconstruction principle of InSAR system and present a complete closed-form solution to the three-dimensional geo-location of targets. Meanwhile we analyse the main error sources, baseline error and interferometric phase error, which influence the precision of digital elevation models (DEM) acquisition. Finally, simulations are made for analyses of the characteristics of baseline error and interferometric phase error, which provides a basis for calibration and correction of systematic parameters.
