Description
Technical field
The utility model relates to reflector arts, more particularly to a kind of three axis inching manual corner reflectors.
Background technique
Interfering synthetic aperture radar technology is handled by the phase information to signal, it can be achieved that high deformation susceptibility,
The advantages of high spatial resolution and face are observed, to compensate for based on (such as triangle/side the measurement, GPS of point observation Geodetic surveying method
And level) low spatial resolution limitation.However, the application of repeat track radar differential interferometry is now subjected to factors
It restricts: first is that time dephasing pass causes serious phase noise；Second is that atmospheric phase delay reduces the reliable of distortion measurements
Property, third is that systematic error caused by the stability problem of radar platform.The time interval of two width SAR images is obtained along repeat track
Longer, the noise of interferometric phase is more serious, i.e., so-called time dephasing is closed, and can lead to distortion measurement (such as vegetation-covered area) mistake
It loses, especially makes long-term accumulated deformation (before such as Earthquake and deformation, city sedimentation, high-speed railway sedimentation, volcanic activity after shake)
Monitoring become difficult；Due to a lack of the high-resolution ground meteorological data synchronous with SAR imaging time, deducted from result of interference
The influence of atmosphere is also extremely difficult；Since the radar platform of manufacturer's production is there are certain stability problem, part is certainly existed
The influence of systematic error reduces so as to cause the precision of observed result.
In view of the above problems, domestic and foreign scholars have carried out a large amount of research and experiment, wherein Italian Ferretti etc.
It proposes and carries out tracking observation using to the stable Permanent scatterers PS of ground signal reflex, dephasing is closed and atmosphere prolongs to weaken
Slow influence.PS refer to extracted in observation area some have stable and high reflex strength target (including it is natural and
Man-made features), for these targets due to reflected intensity height, noise is relatively high, and it is small by external interference, so as to obtain high reliablity
Data analysis result.However, not being all the presence of this PS point everywhere in observation area, PS point is distributed to reach us
With the requirement of quantity, especially in meadow or farmland region, the extraction of PS point is more difficult, it is therefore necessary to carry out artificial laying
Encryption, this artificial PS are exactly the manual corner reflector described in us, it can be achieved that the high intensity to signal reflects.Currently,
The manual corner reflector used is all fixed, that is, is fixedly mounted on observation area.This manual corner reflector is by fixed pedestal
With reflection mark composition, when use, first has to build fixed pedestal in survey region, then will reflection mark it is fixed on the base, reflection
The posture of device is adjusted in construction by construction personnel.
Although this scheme efficiently solves the problems, such as that dephasing is closed in radar interference and atmosphere negatively affects, in reality
In, the application of fixed manual corner reflector due to by natural environment and human factor influenced there is also it is following not
Foot:
1, reflector is fixedly mounted on the pedestal in field, and the position of reflector cannot be adjusted；
2, reflector is fixed on the pedestal in field, cannot carry movement, and reflector is easy to be not easy by natural environment influence
Maintenance, and reflector is usually metal material, is easy to appear stolen situation.

Further, it is provided with the regulating device for adjusting reflector XYZ axis direction position in high precision in pedestal, reflects
The lower end of body and regulating device slidable connection.
Further, pedestal includes the first pedestal and the second pedestal, and regulating device includes for adjusting reflector Y direction
First regulating device of position, the second regulating device for adjusting reflector X-direction position and for adjusting reflector Z axis
The third regulating device of direction position, the first regulating device are mounted on the first pedestal, and the second regulating device and third adjust dress
It sets and is installed on the second pedestal, the lower end of the lower end of reflector and the first regulating device slidable connection, the first pedestal is distinguished
With the second regulating device and third regulating device slidable connection.
Further, the first regulating device, the second regulating device and third regulating device are respectively Y-axis final motion screw, X-axis
The lower end of final motion screw and Z axis final motion screw, reflector is fixedly connected with the traveling nut of Y-axis final motion screw, the first pedestal
Lower end is fixedly connected with the rack in the traveling nut and Z axis final motion screw in X-axis final motion screw respectively.
Further, reflector include one piece of bottom plate and two blocks of side plates, the both sides of one block of side plate respectively with another block of side plate
On one side with bottom plate while be fixedly connected, two blocks of side plates are vertical with bottom plate.
Further, the structure of bottom plate and two blocks of side plates is isosceles triangle.
The utility model has the beneficial effects that:
1, by the effect of pedestal, position of the reflector on three directions of XYZ axis can be adjusted, changes biography
Reflector is fixed the state that cannot be adjusted on the base by system, while being also avoided causing when manually installed manually accidentally
The situation of difference, ensure that the accuracy of reflector to a greater extent；
2, by the way that the structure being integrated is arranged in pedestal and reflector, but pedestal is not fixedly connected directly with ground, is used
When can be met by original observation pier PS point laying requirement, PS point cloth can also be met by being fixed on tripod
If requirement, can also be carried out after use carry be moved to safe place, not only avoid the influence of field natural environment, together
When also avoid stolen possibility.
