RADAR METHOD FOR MONITORING THE GEODETIC SITE OF HIGH-ALTITUDE HYDROELECTRIC DAMS Russian patent published in 2021 - IPC G01B21/22 G01B21/32 G01S5/14 G01S13/88 

FIELD: radar system.

SUBSTANCE: invention relates to a radar system and can be used for operational monitoring of the deviation from the vertical of high-rise buildings, television towers and other building structures. In the claimed method, a system of reflective corner markers is installed along the upper site. The dam site is remotely irradiated with a radar and the phase difference of the carrier frequency of the radiated and reflected radio signals from the markers is measured. The system is supplemented with a reference marker installed on the shore next to the dam. The markers are alternately modulated by low-frequency signals, and the phase of the signal reflected from the reference marker is measured and stored in the radar receiver, which is then compared with the phase of the signal from the first marker installed on the site. Geometric displacements between neighboring markers are distinguished from the phase difference. After irradiation of all markers, an envelope of geometric displacements of the dam blocks (the geodetic site) is constructed.

EFFECT: implementation of remote operational monitoring of large construction structures such as dams of hydroelectric power plants with high accuracy in any weather conditions.
