首先，使用新的Sentinel-1合成孔径雷达的结果看起来非常有希望，但在TOPS模式下获取的特殊干涉宽测绘带数据使得InSAR处理比常规条带模式数据更具挑战性。每个猝发中陡峭的方位谱斜率导致了非常严格的联合配准要求。将单个突发和子条带的数据组合到一致的马赛克中需要在处理数据和元数据时仔细地“记账”，而大文件大小和高数据吞吐量也需要良好的性能。考虑到这些挑战，来自软件的良好支持变得越来越重要。在这篇文章中，我们描述了伽马软件中的哨兵-1支持，伽马软件是研究人员、服务提供商和操作用户在其SAR、InSAR、PSI和偏移跟踪工作中使用的高级软件包。
Abstract First results using the new Sentinel-1 SAR look very promising but the special interferometric wide-swath data acquired in the TOPS mode makes InSAR processing more challenging than for normal stripmap mode data. The steep azimuth spectra ramp in each burst results in very stringent co-registration requirements. Combining the data of the individual bursts and sub-swaths into consistent mosaics requires careful “book-keeping” in the handling of the data and meta data and the large file sizes and high data throughputs require also a good performance. Considering these challenges good support from software is getting increasingly important. In this contribution we describe the Sentinel-1 support in the GAMMA Software, a high-level software package used by researchers, service providers and operational users in their SAR, InSAR, PSI and offset tracking work.
