Problems solved by technology

[0002] INSAR technology is a new and effective method for monitoring geological disasters. The use of INSAR corner reflectors can improve signal strength and accuracy, but it needs to be compared with leveling indicators and GNSS indicators for accuracy. The existing INSAR corner reflectors do not have this function. Cannot integrate GNSS, high-precision level and INSAR technology, and cannot complete the operation requirements of high-precision monitoring of ground and ground subsidence

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] Such as figure 1 As shown, the INSAR corner reflector is composed of a podium 10 , a base 5 , a corner reflector 1 , a GNSS connection hole 8 , and a benchmark 9 . The plinth 10 is a reinforced concrete structure, the size is 500mm (diameter) * 2000mm (height), the underground foundation is 1800 * 1800 * 1200 (300) mm, the top contains a fixed column 6 connected to the base 5, and the corner reflector 1 is made of A cone composed of three 3mm thick isosceles right triangle aluminum plates, the length of the right angle side of the isosceles right triangle aluminum plate is 1200mm; there is a 40mm angle iron frame at the joint between the aluminum plates. The corner reflector 1 is provided with a Ф=15mm right-angle bottom hole to facilitate water leakage and dust; the circular steel plate with a diameter of Ф=360mm and a height of 12mm is the bas...

Abstract

The invention discloses an INSAR corner reflector which comprises a pier base, a base and a corner reflector. A fixing embedded part connected with the base is arranged at the top of the pier base, the corner reflector is of a tetrahedral structure and comprises two side faces and one bottom face, a cross shaft is arranged on the bottom face, the corner reflector can rotate around the cross shaft, at least three columns are arranged on the base, the cross shaft enables two columns to be connected together, the bottom ends of the columns are connected with the base, the third column is connected with a corner reflector height elevation angle adjusting rod, the corner reflector height elevation angle adjusting rod is fixed to the corner reflector together, and a GNSS observation connector is arranged on a central point of the base. The INSAR corner reflector enables INSAR observation, GNSS observation and water level observation to be combined together, and switching between the INSAR observation and the GNSS observation can be performed only by turning one screw. The orientation switching of an INSAR satellite can be performed by turning three screws, accordingly device installation is simplified, expenditure is saved, and efficiency is improved.

Description

technical field [0001] The invention relates to an INSAR corner reflector. Background technique [0002] INSAR technology is a new and effective method for monitoring geological disasters. The use of INSAR corner reflectors can improve signal strength and accuracy, but it needs to be compared with leveling indicators and GNSS indicators for accuracy. The existing INSAR corner reflectors do not have this function. The GNSS, high-precision level and INSAR technology cannot be integrated, and the operation requirements of high-precision monitoring of the ground and ground subsidence cannot be fulfilled. Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned deficiencies in the prior art, provide a kind of multifunctional, high-precision INSAR angle reflector, this reflector combines GNSS observation, leveling observation together, the manufacturing structure is simple, observation azimuth angle, observation The conversion betwe...
