Algorithm of data processing in GPR

Special algorithms and methods of data processing have built into the software are usually used to increase the efficiency of subsurface radar sounding with a ground penetrating radar (GPR). They are intended to improve SNR and to present results of a survey of the subsurface in a convenient for operator form. A number of different signal processing algorithms for subsurface probing are developed. Basic attention of this article is concentrated on the algorithm of automatic search for local objects using the Hough transform. Hough transform allows finding defined analytically plane curves, for example, straight lines, circles, ellipses, etc. in the monochrome image. The monochrome image is the image consisting of points of two types which are background points and points of interest. The task of Hough transform is separation the curves formed by points of interest. An example of algorithm of search for hyperbole in GPR image is discussed in the work.
