Description
Technical field
The invention belongs to deformation monitoring fields, and in particular to a kind of basin ground SAR library bank based on long-distance radio communication
Deformation monitoring device.
Background technique
With flourishing for China's water conservancy, China has built a series of Large Hydro-Junction engineerings, monitors task
It is the most important thing in these water-control project later period operational process.Currently, China's water-control project substantially carries out
Comprehensive monitoring to dam body, and part dam has been realized in monitoring automation, such as voe, unrestrained gulf.But for stream
The monitoring of domain reservoir stability is still in infancy, insufficient in view of prior art means, and the range for needing to monitor is public up to tens
In even several hundred kilometers, most of reservoir stability lack effective observation method, the deformation for being unable to watershed library bank is made in real time
Accurate early warning.After reservoir filling, reservoir bank landslide is one of most common geological disaster in hydraulic and hydroelectric engineering, often be will cause
Huge social loss and economic loss, therefore the monitoring of watershed reservoir stability is essential.
The deformation monitoring equipment of China basin reservoir stability mainly has total station, deformation-sensor, three-dimensional laser to sweep at present
Retouch instrument, GPS etc..Total station can be by high-precision continuous observation, acquisition high-precision basin library bank deformation data, but water conservancy water
Electrical engineering is generally built among high mountain gorge, and it is larger that reservoir stability generally climbs difficulty, using total station to reservoir stability into
Row observation can only often obtain a small amount of dotted deformation information, need a large amount of manpower and material resources, and realize full basin covering substantially not
It may.Although deformation-sensor can be realized the automatic collection of data, but its obtain and dotted monitoring information, and later period
Operation expense is very high, and economy is poor.Three-dimensional laser scanner, which can be, realizes large range of observation, but measures
Precision is limited, and timeliness is also poor, cannot in time, accurately obtain the deformation information of basin library bank.GPS in accuracy of observation and
There is apparent advantage in terms of observation scope, but limited by weather and satellite orbit, can not achieve round-the-clock observation.
Ground SAR is a kind of effective distortion measurement technology risen at the beginning of 21 century, which is based on microwave sounding actively
Imaging mode obtains monitoring region bidimensional image, by synthetic aperture and step frequency technology realize radar image distance to and side
Position to high spatial resolution observation, can realize that millimetre-sized Light deformation monitors by interference technique.Ground SAR can be carried out greatly
Range continuous observation, observation cycle is most short to be can achieve several minutes, and has better spatial resolution, in installation and is laid
Aspect also relatively flexibly, can be realized multi-faceted monitoring, obtain the deformation of any direction, so that eliminating the error of baseline influences.
Ground SAR has been obtained in deformation monitoring field and is widely applied.External aspect, Tarchi are equal to 2003
It is come down using the Tessina that ground SAR monitors Italy, as a result compared with traditional optical instrument monitoring result, measures control point
Within the maximum mutual deviation 3mm of displacement.2005, Noferini was observed in the side slope to Italian Citrin Valley
Shi Shouci corrects atmospheric phase, final monitoring estimated result and GPS measurement result in ground SAR system using PS technology
Differ very little.Ventisette monitors the urgent landslide in Italian Calabria area, monitoring result table using ground SAR
Influence of the bright landslide to highway is smaller.Luzi etc. using ground SAR monitor alpine glacier flow velocity, monitoring result and its
His remote sensing technology monitoring result is almost the same.Ground SAR is applied to dyke displacement monitoring by domestic aspect, Liu Hong first-class, it is believed that
Ground SAR can accurately observe dyke surface deformation information.Osiery etc. utilizes ground SAR continuous observation Xinjiang Hejing County iron ore
Superglacial flow velocity, the knot of surface velocity information of mountainous villas can quickly, accurately be obtained by obtaining ground SAR technology
By.Liu little Yang etc. is monitored excavation slope using ground SAR technology, using weighting circumference median filtering filter out thermal noise and
The influence of ambient noise has obtained the SAR image of high quality, by comparing with high precision total station monitoring result, demonstrates ground
Base SAR has submillimeter level precision.
Although ground SAR is widely used in multiple fields, in water-control project especially basin library bank
Monitoring aspect application is less.Monitoring technology traditional at present is not able to satisfy the detection requirement of basin library bank, leads to most of streams
