Global Navigation Satellite System (GNSS) interferometric reflectometry, also known as the GNSS-IR, uses data from geodetic-quality GNSS antennas to extract information about the environment surrounding the antenna. Soil moisture monitoring is one of the most important applications of the GNSS-IR technique. This manuscript presents the main ideas and implementation decisions needed to write the Python code for software tools that transform RINEX format observation and navigation files into an appropriate format for GNSS-IR (which includes the SNR observations and the azimuth and elevation of the satellites) and to determine the reflection height and the adjusted phase and amplitude values of the interferometric wave for each individual satellite track. The main goal of the manuscript is to share the software with the scientific community to introduce new users to the GNSS-IR technique.

用于GNSS干涉反射法（GNSS-IR）的Python软件工具

全球导航卫星系统（GNSS）干涉反射法，也称为GNSS-IR，使用来自大地质量GNSS天线的数据来提取有关天线周围环境的信息。土壤水分监测是GNSS-IR技术最重要的应用之一。该手稿介绍了编写用于将RINEX格式观测和导航文件转换为GNSS-IR的合适格式（包括SNR观测值以及卫星的方位角和仰角）的软件工具的Python代码所需的主要思想和实施决策，以及确定每个卫星轨道的反射高度以及干涉波的调整后的相位和幅度值。
