Embodiment 1
[0027] When performing InSAR remote sensing monitoring, data preparation is the first step. According to the relevant business specifications and data preparation requirements, select the required satellite remote sensing images and basic data, data preprocessing, satellite remote sensing images need to be preprocessed, preprocessing should include the main image Selection and cropping, image registration and combination, DEM and main image registration, simulated elevation phase, etc., generate differential interferograms through differential InSAR technology, including interferometric phase calculation, coherence coefficient estimation, flat terrain phase removal, and differential interferogram generation etc., calculate the surface deformation rate or deformation amount through time-series InSAR technology, mainly calculate the atmospheric delay phase (APS) and deformation phase, make the ground subsidence map, combine the basic data, eliminate the information irrelevant to t...
Embodiment 2
[0029] During ground-assisted real-time remote sensing monitoring, according to the InSAR surface subsidence monitoring census report and field verification results, determine the key prevention and control road sections that need ground-assisted real-time remote sensing monitoring, the type and quantity of equipment to be selected, and formulate construction plans and specific plans. Relevant work requirements and monitoring needs of the unit, procurement of required equipment and sensors, preparation of system integration and construction work, on-site surveys of key prevention and control road sections that need to be monitored, combined with the principle of monitoring point selection, determine the location of equipment layout and basic information such as power and communication. According to the construction requirements, carry out civil construction, install equipment according to equipment installation and commissioning requirements, carry out system integration testing...
