摘　　要：对分布式星载SAR系统地面回波仿真程序并行化算法进行了研究。重点介绍了分布式小卫星SAR系统多星协同工作的仿真策略、各并行节点任务的分配策略和并行节点间大量数据传输的策略。实验证明此并行化算法具有较高的加速性能,具有实际的应用前景。The parallel arithmetic of distribute space borne SAR ground target echo data simulating procedure was examined. The following issues were introduced： the method to simulate the cooperating working mode of distribute space borne SAR system, the policy of allotting tasks between parallel computing nodes, and the policy of transferring massive-data between computing nodes. The experiment proves that the parallel arithmetic has high speed-up performance.
