【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。更多还原

【Abstract】 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.更多还原
