Abstract

The invention provides a geodetic measurement system and an operation method thereof. The geodetic measurement system monitors a target object through a multi-channel radar ranging instrument and returns to receive pulse sequences; after a digital processing module receives the pulse sequences, correlation operation is conducted on each receiving pulse sequence and the corresponding transmitting pulse sequence in sequence to obtain a correlation value, and the correlation values are combined to obtain an accumulated correlation value; the accumulated correlation value is subjected to peak value detection to obtain the maximal peak value, the maximal peak value is compared with a threshold, and the time corresponding to the maximal peak value is obtained when the maximal peak value is higher than the threshold, so that processing equipment can obtain the spatial linear distance of the radar ranging instrument relative to the target object, and the accuracy degree of the spatial linear distance of the target object is increased through a mode of accumulating the correlation values; and due to a multi-antenna combining technology, the combining gain is improved and the measuring distance can be increased.

Description

technical field [0001] The invention relates to the field of geodetic surveying technology, in particular to a geodetic surveying system and an operating method thereof. Background technique [0002] Various geodetic devices for surveying one or more survey points have been known since ancient times. In this case, as standard, spatial data, distances and directions, or angles from the measuring device to the measuring point to be measured are recorded. In particular, the absolute position of the measuring device is acquired together with possibly existing reference points. [0003] Widely known examples of existing geodetic devices include theodolites, tachymeters or total stations, which are also known as electronic tachymeters or computer tachymeters. [0004] However, the existing geodetic devices are susceptible to atmospheric factors and have certain systematic errors, and the multipath effects caused by terrain factors in conventional laser ranging lead to large erro...
