The invention discloses a high-precision slope deformation monitoring system, which solves the problem of high-precision slope deformation monitoring by using an acquisition device and a signal sending and receiving and processing device. A number of corner reflectors are set on the slope, and the corner reflectors will deform correspondingly with the deformation of the slope; a signal transceiver and processing device is set on one side of the slope, which transmits frequency-modulated continuous wave signals to the acquisition device, and the frequency-modulated continuous wave After the signal is reflected by the acquisition device, it is collected by the signal transceiver and processing device to form an intermediate frequency echo signal. The intermediate frequency echo signal is processed through the imaging processing of the signal transceiver and processing device and the slope deformation is extracted to realize two-dimensional deformation monitoring of the slope. The slope deformation monitoring system provided by the present invention overcomes the shortcomings of the existing ground two-dimensional deformation radar that is expensive and difficult to deploy and apply in batches. Quantitative extraction method is used to realize high-precision and low-cost slope deformation monitoring.
Description
technical field [0001] The invention relates to the technical field of ground deformation monitoring radar, in particular to a high-precision slope deformation monitoring system and method. Background technique [0002] The geological conditions of slopes in my country are complex, and sudden surface cracking, subsidence, displacement and other disasters often occur under the action of external forces. Landslides often cause huge losses, and some even devastating disasters, to industrial and agricultural production and people's lives and property. High-precision real-time monitoring of slope deformation is necessary. The existing main slope deformation monitoring methods include total station, differential GPS, ground-based two-dimensional deformation monitoring radar, space-based GNSS and InSAR timing method: the total station belongs to the optical measurement system, and its accuracy can reach submillimeter level. It is greatly affected by weather and environmental factor...
