Abstract

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.

基于被动北斗B3I信号雷达的变形监测:概念验证实验演示

中国的北斗导航系统已经建成，目前正在运行。北斗三号是最新的星座，由30颗卫星组成。虽然北斗-3的应用发展迅速，但利用北斗-3信号作为信号资源在全球导航卫星系统(GNSS)无源雷达域监测变形的可行性尚未得到证实。本文作者设计了BD-3型无源雷达模型，并进行了变形监测的概念验证实验演示。验证了以B3I信号为信号源进行GNSS雷达(GNSS- r)变形监测的方法是可行的。实验场景包括实验室模拟和现场位移变形的概念验证。仿真场景的测试误差为0.023 m，基于目标平移测量的变形现场场景测试误差为0.0435 m，基于目标旋转测量的变形现场场景测试误差为0.1011 m。

期刊介绍： The journal publishes original research papers in the field of geodesy and geophysics under headings: aeronomy and space physics, electromagnetic studies, geodesy and gravimetry, geodynamics, geomathematics, rock physics, seismology, solid earth physics, history. Papers dealing with problems of the Carpathian region and its surroundings are preferred. Similarly, papers on topics traditionally covered by Hungarian geodesists and geophysicists (e.g. robust estimations, geoid, EM properties of the Earth’s crust, geomagnetic pulsations and seismological risk) are especially welcome.
