Distributed satellites bistatic SAR can be considered as a kind of bistatic/multi-static SAR system, whose transmitters and receivers move in parallel. Based on this, in this paper, the geometry resolution of distributed satellites SAR is analyzed using the concept of gradient. The formulas of resolution characteristics, such as geometry resolution, the direction of resolution vector and the area of resolution cell, are deduced in the form of look angle and squint angles functions. In addition, the influence of satellites baselines on the geometry resolution is also discussed, and the simulated results are also provided here.
