Problems solved by technology

However, at present, the existing corner reflectors fail to achieve simultaneous observation with the national high-level leveling survey, so the leveling values ​​obtained through approximate processing are difficult to reflect the real settlement of the corner reflector, and cannot meet the application of high-precision regional ground subsidence monitoring need

Embodiment

[0019] The present invention will be further described below in conjunction with accompanying drawings and examples of implementation

[0020] Level / InSAR integrated monitoring device, including:

[0021] Base; 4 stone pillars mounted on the base; first-class leveling mark mounted on one of the stone pillars; 1 corner reflector mounted on the remaining 3 stone pillars.

[0022] The base is a reinforced concrete structure, with a length of 1200mm, a width of 1200mm, and a height of 200mm; the steel skeleton of the base is composed of 9*9 round steels with a diameter of 10mm, and the spacing is 140mm.

[0023] In the middle of the base, according to the design position of the corner reflector and the benchmarking point, make four stone pillars. The length of the pillars is 200mm, the width is 200mm, and the height is 1000mm. Reserve 100mm of round steel with a diameter of 10mm for corner reflector welding.

[0024] The triangle side lengths of the corner reflector base are 630...

Abstract

The invention relates to ground subsidence monitoring, and further relates to a level / InSAR integrated monitoring device. The level / InSAR integrated monitoring device achieves integrated monitoring of corner reflector monitoring and standard monitoring synchronously. The level / InSAR integrated monitoring device comprises a base, N identification cylinders installed on the base, a level measuring marker installed on one identification cylinder and corner reflectors installed on the other N-1 identification cylinders, wherein N is larger than or equal to 2. Compared with the prior art, the level / InSAR integrated monitoring device has the advantages that InSAR data processing error control can be achieved by means of the high-precision level result, and then the InSAR monitoring ground subsidence precision and stability are improved.

Description

Technical field: [0001] The invention relates to ground subsidence monitoring, and further relates to a level / InSAR integrated monitoring device. Background technique: [0002] As an important means of remote sensing and ground monitoring, synthetic aperture radar interferometry can realize the settlement of various surface objects. The use of InSAR corner reflectors can compensate for data decoherence, improve the accuracy of data processing, and achieve reference control. However, at present, the existing corner reflectors fail to achieve simultaneous observation with the national high-level leveling survey, so the leveling measurement values ​​obtained through approximate processing are difficult to reflect the real settlement of the corner reflector, and cannot meet the application of high-precision regional ground subsidence monitoring need. Invention content: [0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior ...
