Embodiment Construction

[0055] The invention will be further described below in conjunction with the accompanying drawings.

[0056] like figure 1 , figure 2 As shown, a ground penetrating radar data processing method, the interface development environment of RAILGPR1.0 of this method is Visual C++2005, the core calculation language is MATLAB 7.1, the MATLAB engine is called through the VC in the foreground, and MATLAB is used in the Background calculations.

[0057] 1. General steps of program operation:

[0058] a. Single data processing

[0059] Ground penetrating radar data processing method The main function of RAILGPR1.0 data processing is to remove clutter and improve the resolution of radar profile; clutter can be divided into two types, one is caused by the ground penetrating radar hardware itself and its working mode, is fixed, the other is caused by the properties of the medium and the surrounding environment during detection, and is different with the external conditions; therefore, ...

Abstract

The invention relates to a method for processing ground penetrating radar data. The method chooses Visual C++2005 as RAILGPR1.0 interface development environment, adopts MATLAB 7.1 as a calculation kernel language, calls MATLAB engine through foreground VC, and uses MATLAB in the background for calculation. Compared with the prior art, the method has a read display function, a data processing function, an automatic interpretation function and a plurality of other functions.

Description

technical field [0001] The invention relates to the technical field of radar detection and its application, in particular to a ground-penetrating radar data processing method. Background technique [0002] In the 1980s, ground penetrating radar was introduced into the detection of railway embankment, related experiments and researches were carried out rapidly in various countries in the world, and some progress was made. Although with the continuous update and development of ground penetrating radar hardware, its sampling speed, timely display technology, detection depth and accuracy have been improved to varying degrees. [0003] However, almost all GPR supporting system software can only provide data acquisition and simple data processing functions. The performance cannot be easily understood by the construction workers on site. The result interpretation is always under the constraints of the traditional geophysical data interpretation, that is: first print the radar tim...
