| 摘要: |
| 为克服常规的InSAR处理性能评估方法只能分析整体性能的缺点，提出一种适用于分布式星载InSAR的理想干涉相位图仿真算法，此算法不仅能得到理想干涉相位，而且能得到理想情况下的配准偏移量。在此基础之上，提出一种基于理想干涉相位及理想配准偏移量（统称为理想干涉量）的InSAR处理性能评估新方法。此方法可以有效隔离InSAR处理流程各个环节的误差，对InSAR处理流程的各个环节的算法优化具有重要的实用价值。 |

| Abstract: |
| Only the final performance of InSAR processing is evaluated in normal evaluation method. In this regard, an algorithm for interferometric phase simulation is presented in the hope that it is applicable to distributed spaceborne InSAR (Interferometric Synthetic Aperture Radar). Not only the perfect interferometric phase but also the perfect co-registration offset are generated in this algorithm. A novel method for InSAR performance evaluation is proposed, which is based on perfect interferometric phase and perfect co-registration offset. With this method, the errors of each step of InSAR processing can be isolated. Furthermore, performance of InSAR processing algorithm can be evaluated. |
