中国的北斗导航系统已经建成，目前正在运行。BD-3星座是我国最新的星座，由30颗卫星组成。BD-3的应用已经得到了迅速的提高，然而，使用BD-3信号作为全球导航卫星系统（GNSS）无源雷达领域的信号源来监测变形尚未被证明是可行的。本文作者设计了BD-3被动雷达模型，并进行了变形监测的概念验证实验演示。结果表明，基于B3 I信号作为GNSS雷达（GNSS-R）形变监测信号源的方法是可行的。实验方案包括实验室模拟和现场位移变形的概念验证。测试误差对于模拟场景达到0.023 m的值，对于基于目标平移测量的变形的现场场景达到0.0435 m的值，并且对于基于目标旋转测量的变形的现场场景达到0.1011 m的值。
China’s BeiDou navigation system has been completed and is currently in operation. As the newest constellation, BD-3 is composed of 30 satellite configurations. The application of BD-3 has improved rapidly, however, using the BD-3 signal as a signal resource in the global navigation satellite system (GNSS) passive radar domain to monitor deformation has not been proven to be feasible. The authors of his paper designed a BD-3 passive radar model and carried out a proof-of-concept experimental demonstration for deformation monitoring. As a result, a method based on the B3I signal as a signal resource for GNSS radar (GNSS-R) deformation monitoring is proven to be feasible. The experimental scenarios include laboratory simulation and proof of concept field displacement deformation. The test error reaches a value of 0.023 m for a simulation scenario, 0.0435 m for a field scene of deformation based on a target translation measurement, and 0.1011 m for a field scene of deformation based on a target rotation measurement.
