Environmental benefit.
InSAR data impact analysis carries out D-InSAR differential SAR Interferometry analyses first, selectes Space Baseline and interference
It is right, interfered, landform phase difference, filtering, solution twine processing；Then centainly model is collapsed using interpolation accumulation stack result extraction
Contour；Later, it while obtaining sinking land in coalmining areas totality deformation data using multi-baseline interference accumulation of phase stacking method, obtains
Changing character；Finally, multidate SAR Strength Changes detection side is utilized after the range of satellite image extracting data pools zone
Method carries out pools zone identification.
The selected a certain area in southwest in Shandong Province, carries out D-InSAR differential SAR Interferometry analyses, is less than to meeting time reference line first
200 days, less than 34 of 300 meters interference pair of Space Baseline are selected, are interfered, landform phase difference, filtering, solution twine processing,
Specifically use two rail difference processing methods.
It is extracted using interpolation accumulation stack result and centainly collapses range line, selection collapses 5cm range line drawings, sees and extracted
Range wire shaped.
The apparent region of depression is taken from 5cm range line selections are collapsed, is obtained using multi-baseline interference accumulation of phase stacking method
While the totality deformation data of the sinking land in coalmining areas, changing character is obtained.
Follow-up 5cm ranges line drawing is used for as this mining area InSAR monitoring results using more baselines accumulation stack result.
Stacking method correlation analysis is accumulated according to more baselines, is supervised more than InSAR deformation using non-interpolation accumulation stack result for extracting
" the null value area " of survey ability extracts, and null value area is included in 5cm range lines；It is collapsed using interpolation accumulation stack result for extracting
5cm range lines.
Deformation results are superimposed to accumulation, the 5cm automatically extracted by deformation magnitude collapses line of demarcation, it can be seen that in mining area model
Monitor that the activity that collapses in multiple goafs, gob collapse spatially show as funnel shaped, draw with mining area exploitation in enclosing
The surface subsidence space characteristics risen meet preferable.
While more baseline accumulations are superimposed upon to obtain mining area totality deformation data, it can also reflect that mining area deformation occurs well
Process.From the apparent region of multiple sedimentations that accumulation deformation results are selected, and multiple characteristic points are chosen, carries out multiple regions respectively
The changing character of sedimentation is analyzed, and the period is by taking in April, 2013 in October, 2015 as an example.
By taking the A1 of certain point as an example, its sequential change procedure is analyzed, point A1 settling characteristics are apparent, and subsiding center more connects
It is continuous.Its deformation generating process is further analyzed, mining area deformation is relatively stable between June in April, 2013-, and in June, 2013-, September occurred
The trend of deformation aggravation；Deformation is more steady between in September, 2013 in June ,-2014, between in June, 2014-September deformation further add
It is acute；Deformation is steady between in September, 2014 in May ,-2015, and October in May, 2015-, deformation tendency is further exacerbated by；Therefore, the area
In domain between in October, -2015 in April, 2013, deformation was happened between annual 5, June -9, October, be rendered as it is non-linear by
Increased process is walked, as shown in Figure 6.
Multidate SAR Strength Changes detection methods are utilized after the range of satellite image extracting data pools zone, carry out ponding
Area identifies.On SAR images, black or dead color is generally presented in water body, pools zone can be identified according to this feature,
More scape images are regarded more using multidate SAR Strength Changes detection method, accuracy registration, multidate filter, geocoding
With radiation correction etc. processing.According to pools zone sequential intensity map, observation judges pools zone range in a certain period of time.
Data concentrate on a platform realizing the unified display of data base, as shown in Figure 2-5, form mining and collapse
Fall into ground dynamic monitoring management system centralized displaying.
The accuracy of InSAR monitoring results passes through 60 monitoring points randomly selected in thousands of working faces in a certain mining area
For, eyeball and InSAR monitoring results are compared respectively, monitoring time 20141005,20141122,20141207,
20141221,20150110,20150131,20150214,20150322,20150523 and 20150627.Corresponding SAR
Data obtaining time 20140921,20141202,20150212,20150401,20150519,20150730.
When carrying out precision test, it should ensure that the date of the two is consistent as possible, or the difference time is little.Therefore it selects
20141005-20141207 and 20140921-20141202,20141005-20150214 and 20140921-20150212 and
The data of tri- periods of 20141005-20150523 and 20140921-20150519 carry out precision test respectively.
As shown in fig. 7, as can be seen from the figure observation and InSAR value variation tendencies are more consistent, actual observed value with
The average error of InSAR values is 0.013m, coincidence loss requirement.
Certainly, described above is only that presently preferred embodiments of the present invention is answered the present invention is not limited to enumerate above-described embodiment
