GNSS-R TARPP v1 (Topography) Algorithm Test Data

Lucinda King 08-03-2021<br>This is the data release which accompanies the MDPI Remote Sensing article "Towards a Topographically Accurate Reflection Point Prediction Algorithm for Operational Spaceborne GNSS Reflectometry" King. L et al 2021.<br>These data were used in the study described in the article. <br>The contents of the release are as follows. <br>- RawData: A folder of matfiles containing the DDMs for the six test datasets, for all PRNs, processed with both the quasispherical model and TARPP with 3 DEM resolutions.- extractDDM_array_pub.m is a MATLAB script for extracting the DDM arrays from the matfiles. It operates based on the current subfolder structure. - track_metadata.xlsx is an spreadsheet containing the metadata of the datasets.- The kml_files show the position of the dataset collections on the Earth's surface.- The data is released under a CC BY 4.0 licence - the full license text can be found in the license.txt file. It should be attributed to Surrey Satellite Technology Ltd. (SSTL) and Lucinda King.

本数据集为配套MDPI《遥感》（Remote Sensing）期刊论文《面向星载全球导航卫星系统（Global Navigation Satellite System，GNSS）反射测量业务化运行的地形精确反射点预测算法》（King L等，2021）发布的数据资源，该数据集用于支撑上述论文中的研究工作。
本数据集包含以下内容：
- 原始数据文件夹（RawData）：内含6个测试数据集的所有伪随机噪声码（PRN）对应的延迟多普勒图（Delay Doppler Map，DDM）的MATLAB数据文件（.mat），所有延迟多普勒图均采用准球面模型与三种数字高程模型（DEM）分辨率下的TARPP算法完成处理。
- extractDDM_array_pub.m：用于从MATLAB数据文件中提取延迟多普勒图阵列的MATLAB脚本，运行逻辑基于当前子文件夹结构。
- track_metadata.xlsx：包含本数据集元数据的电子表格文件。
- kml_files：内含用于展示数据集采集点位在地球表面分布情况的KML文件的文件夹。
- 本数据集采用知识共享署名4.0（CC BY 4.0）许可协议发布，完整许可文本可在license.txt文件中查阅。数据集引用需标注萨里卫星技术有限公司（Surrey Satellite Technology Ltd.，SSTL）与露辛达·金。
