Title:
DEFORMATION MEASUREMENT METHOD AND RADAR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/197064
Kind Code:
A1
Abstract:
A deformation measurement method, comprising: obtaining a first echo signal of a first monitoring point of a monitoring target and a second echo signal of a second monitoring point (S100); obtaining a first sight line deformation amount and a second sight line deformation amount of the monitoring target according to the first echo signal and the second echo signal (S200, S300); and calculating a vertical displacement and/or a horizontal displacement of the monitoring target according to the installation parameters of a radar device, the first sight line deformation amount, and the second sight line deformation amount (S400). Also provided is a radar system. The environmental adaptability and measurement accuracy of the radar system can be improved, so that the radar device is convenient to install.
