Shallow Ice Radar (SIR) Dataset from Ross Ice Shelf (ROSETTA-Ice)

This Shallow Ice Radar (SIR) dataset is from the Frequency Modulated Continuous Wave (LFMCW) radar system on board the IcePod while deployed with the ROSETTA-Ice project during the austral summers of November 2015 - December 2017. SIR data was collected along the ROSETTA-Ice Survey Grid where possible. More detailed information is included in the ReadMe. This data was processed at Lamont-Doherty Earth Observatory using MATLAB scripts developed in-house by Tejendra Dhakal and Nicholas Frearson, using CReSIS 2013/14 MCoRDS scripts as a foundation. All levels of processed data are Matfiles as a result.
Included in this dataset are the following:
* SIR level1a Matfiles separated by ROSETTA-Ice Survey Grid Line Number;
* SIR long-line images at 300dpi (PNGs) for easy data viewing, rendered in MATLAB from level1 data;
* SIR internal reflector digitization picks (CSV), rendered manually using MATLAB picking scripts;
* SIR digitization frame images (picked and un-picked) as JPGs output from picking process

本浅层冰雷达（SIR）数据集源自搭载于冰Pod上的频率调制连续波（LFMCW）雷达系统，该系统在ROSETTA-Ice项目期间，于2015年11月至2017年12月的南半球夏季进行部署。SIR数据在尽可能的ROSETTA-Ice调查网格沿线进行采集。更详细的信息包含在ReadMe文件中。这些数据在拉蒙特-道格拉斯地球观测站进行处理，采用由Tejendra Dhakal和Nicholas Frearson内部开发的MATLAB脚本进行处理，以CReSIS 2013/14 MCoRDS脚本为基础。所有处理级别的数据均为Matfiles格式。
本数据集包含以下内容：
* 按ROSETTA-Ice调查网格行号分隔的SIR level1a Matfiles；
* SIR长线图像（PNG格式，300dpi），便于数据查看，由MATLAB从level1数据渲染；
* SIR内部反射器数字化选取（CSV格式），使用MATLAB选取脚本手动渲染；
* SIR数字化帧图像（选取与非选取），以JPG格式输出自选取过程。
