Problems solved by technology

[0006] However, in my country, artificial leveling is mainly used for safety monitoring of slopes. This method takes a long time to measure and has low precision, and cannot monitor dangerous slope areas; very few mines use total stations, GPS and other technologies to monitor artificially selected areas. The method of contact measurement at discrete points is used to monitor the safety of slopes. This method cannot comprehensively and quickly reflect the overall displacement of the monitored target,

Embodiment

[0032] figure 1 A flow chart of a ground-based synthetic aperture radar-based slope safety monitoring and early warning method provided by an embodiment of the present invention, as shown in figure 1 As shown, the method mainly includes:

[0033] Step 11. Obtain the raw radar data of the monitored slope area periodically sent by the ground-based synthetic aperture radar, where the raw radar data sent for the first time is denoted as s 0 , the original radar data sent in the nth observation cycle is denoted as s n , where n represents the observation period, and n≥1.

[0034] In the embodiment of the present invention, the ground-based synthetic aperture radar is placed statically, and its transmitting / receiving antenna beam illuminates the monitored slope area. At a certain moment, it receives the control parameters and start-up instructions from the remote monitoring center, and performs a radar data collection. The original data collected for the first time The data is reco...

Abstract

The invention discloses a side slope safety monitoring and prewarning method based on ground-based synthetic aperture radar. The side slope safety monitoring and prewarning method includes acquiring radar data, about continuous fixed point observation, of a side slope area by the ground-based synthetic aperture radar; subjecting the radar data which are acquired to imaging processing, differential interference processing and deformation information extracting; performing side slope slip analysis, prediction and automatic prewarning. By the side slope safety monitoring and prewarning method, all-time, all-weather, remote-distance, high-accuracy and fixed-point continuous monitoring of the large-range side slope area can be realized, and acoustic, optical and electric signal prewarning can be realized automatically.

Description

technical field [0001] The invention relates to a technology for predicting slope slipping and deformation, in particular to a method for monitoring and early warning of slope safety based on ground-based synthetic aperture radar. Background technique [0002] my country is currently in a period of large-scale construction, and a large number of slope projects have appeared in various construction fields such as mining, water conservancy, transportation and construction, such as mine slopes, dam abutment slopes, reservoir bank slopes, railways and highways These slopes have the characteristics of large scale, large number, complex environment and geological conditions. In the field of mining alone, my country has about 70,000 open-pit mines, 12,000 tailing ponds, and 100,000 dumps, which are very large in number. With the continuous development of the national economy and the country's continuous demand for energy and power, the number of slopes excavated and filled in minin...
