Abstract

Abstract: System simulation test is of great significance to the verification of spaceborne InSAR system overall design and key technologies. Performance evaluation is one of the main steps. An InSAR performance index set is established, which is divided into three main categories and is constituted of eight indexes. A novel method for InSAR system simulation performance evaluation is proposed based on Stamp Points. In this method, some Stamp Points are reasonably laid in the ground simulation scene and all the indexes are calculated by treating these Stamp Points as sample points. Compared with the ideal interferometric factors evaluation method, this method is more robust, and has similar accuracy. Finally, simulation results verify the validity of this method.

摘要： 系统仿真实验对于天基InSAR系统的总体设计和关键技术验证意义重大，性能评估是其中的关键环节之一。建立了由三大类共8项指标组成的InSAR系统性能指标体系，提出了基于标志点的InSAR系统仿真性能评估方法。该方法通过在仿真地面场景中合理布设标志点，并以标志点作为评估样本点来计算各项指标，可达到与理想干涉量评估方法相近的指标计算精度，同时避免了理想干涉量评估方法稳健性不足的问题，且计算效率更高。仿真实验结果验证了评估方法的有效性。
