MATLAB utilities for Sentinel-1 Level 1 datasets ================================================ This repository contains several MATLAB functions to read and prepare/process Sentinel-1 Level 1 datasets. These functions were developed primarily to work with single-look complex (SLC) images acquired in TOPS mode, i.e. Sentinel-1's Interferometric Wide Swath (IW) or Extra Wide Swath (EW) modes. Expected compatibility with the StripMap (SM) and Wave (WV) modes, and with ground-range detected (GRD) images, is indicated for each function. ## List of functions __NOTE:__ These functions may not work with MATLAB versions older than R2016b. The `USAGE` file provides indications on how to use some functions. + `parseSafeManifest`: Extract useful information from the `manifest.safe` file of a Sentinel-1 dataset. This function should work with any Sentinel-1 Level 1 dataset. + `readSent1Data`: Read data in a Sentinel-1 measurement TIFF file. This function should work with any Sentinel-1 Level 1 image. + `applySent1Lut`: Apply a calibration LUT to a Sentinel-1 SLC image. This function should be compatible with SLC images in all modes. It has not been tested with GRD images. + `private/getTIFFinfo`: Extract useful parameters from a TIFF file, e.g. information used to read it, and perform basic checks. This function should work with any Sentinel-1 measurement TIFF file, but also for RADARSAT-2 images in the BigTIFF format. Additional functions in the `dev` branch (under development or not fully tested): + `mergeSent1TopsBursts`: Stitch (merge) bursts in a TOPS subswath. Applicable only to IW and EW SLC images. + `topsDeramping`: Deramp TOPS data in azimuth. Applicable only to IW and EW SLC images. Some of these functions use the [`xmlExtract` utility](https://github.com/lprouss/xmlExtract), which provides an (arguably) easier way to extract data from XML files, like Sentinel-1's annotation files. This function, as well as its associated sub-functions, should thus be present in MATLAB's search path. 该存储库包含几个MATLAB函数，用于读取和准备/处理Sentinel-1 Level 1数据集。 开发这些功能主要是为了与以TOPS模式（即Sentinel-1的干涉宽幅（IW）或超宽幅（EW）模式）获取的单视复杂（SLC）图像一起使用。每个功能均指示与StripMap（SM）和Wave（WV）模式以及与地面检测（GRD）图像的预期兼容性。 ##功能列表 __注意：__这些函数可能不适用于低于R2016b的MATLAB版本。 “使用”文件提供了有关如何使用某些功能的指示。 +`parseSafeManifest`：从Sentinel-1数据集的`manifest.safe`文件中提取有用的信息。此功能应与任何Sentinel-1 Level 1数据集一起使用。 +`readSent1Data`：读取Sentinel-1测量TIFF文件中的数据。此功能应适用于任何Sentinel-1 Level 1图像。 +`applySent1Lut`：将校准LUT应用于Sentinel-1 SLC图像。在所有模式下，此功能均应与SLC图像兼容。尚未使用GRD图像进行测试。 +`private / getTIFFinfo`：从TIFF文件中提取有用的参数，例如用于阅读和执行基本检查的信息。此功能应适用于任何Sentinel-1测量TIFF文件，但也适用于BigTIFF格式的RADARSAT-2图像。 `dev`分支中的其他功能（正在开发中或未经过全面测试）： +`mergeSent1TopsBursts`：缝合（合并）在TOPS分支中爆发。仅适用于IW和EW SLC图像。 +`topsDeramping`：以方位角表示Deramp TOPS数据。仅适用于IW和EW SLC图像。 其中一些功能使用[`xmlExtract`实用程序]（https://github.com/lprouss/xmlExtract），它提供了一种从Sentinel-1注释文件中提取XML文件中的数据的方法（可以说是更简单）。因此，该函数及其关联的子函数应该出现在MATLAB的搜索路径中。
