Description

technical field [0001] The invention relates to a positionable ground penetrating radar. Background technique [0002] GPR (Ground Penetrating Radar, Ground Penetrating Radar) is a geophysical exploration method that uses ultra-high-frequency pulsed electromagnetic waves to detect target underground media. The above-mentioned target underground media specifically include: groundwater, bedrock surfaces, pipelines, etc. A broad-spectrum (1MHz-1GHz) electromagnetic technique used to determine the distribution of underground media has been widely used in hydrology, engineering, environment, mining and other fields, and its application range is still expanding. [0003] The workflow of GPR detection includes: ①The characteristics of the target subsurface medium, environmental analysis, and network layout; ②Selection of characteristic parameters to be measured and on-site detection; ③Processing and interpretation of characteristic parameters. In the prior art, the processing and ...

Problems solved by technology

In the prior art, the processing and interpretation of the characteristic parameters of ground penetrating radar has been relatively mature. However, in the actual processing of the characteristic parameters to be measured, the ground surface can only be regarded as a plane, and the influence of terrain fluctuations on the detection results is completely ignored. It is not conducive to the identification of the radar wave event. Even if the survey line is arranged according to the data such as remote sensing images or topographic maps, due to the complexity of the actual situation on the site, it is difficult to find the reference object for the survey line layout, and it is difficult to To ensure the accuracy of the survey line layout, in addition, in the management of the characteristic parameters of the ground penetrating radar, the file form is mostly used, the management is single, and the application of radar data information and digitization is low, especially in the conditions of complex terrain and wide area These problems are more prominent when doing a lot of field detection work under
