Abstract

The invention relates to a direct ray tracking algorithm for geological radar chromatography detecting and belongs to the field of physical geography inversion algorithms. The method comprises the following steps that a plane right-angle relative coordinate system is established; a section is subjected to mesh generation and numbering; the left-right marking point coordinates of each mesh are determined; the coordinates of an emitting point and a receiving point are determined; ray parameters are computed; the lengths of the rays in the meshes are computed; the computing results are checked; and the computing results are subjected to sparse storage. According to three parameters of the left intercept, the right intercept and the slope of the rays, the ray trend is tracked, only the meshes through which the rays pass need to be computed, compared with a traditional algorithm in which all the meshes are traversed, consumption on internal storage and time is greatly lowered, the efficiency and the accuracy of the algorithm are improved, finally the computing results are stored in a sparse format, storage space can be saved, and the distribution status of the rays can be visually displayed.

Description

technical field [0001] The invention belongs to the field of geophysical inversion algorithms, and relates to a linear ray tracing algorithm for geological radar tomography detection. Background technique [0002] Geological radar technology is a fast, non-destructive and efficient geophysical detection technology. In recent years, its application in mines has gradually increased, such as the detection of hidden dangers such as coal mine aquifers, collapsed columns, fissure zones and gas outbursts. At present, ground radar mainly adopts reflection echo technology, and the detection depth is limited to 30-50 meters. Since the distance between the roadways in the mining area of ​​modern mines is often greater than 200 meters, the geological radar cannot reach the required detection depth when detecting the disaster source in the coal mining face. [0003] The tomographic detection technology is a new direction in the field of geological radar. By collecting the travel time or...
