Geological radar is the recent development of the underground targets of the effective means of detection, at home and abroad have been very widely used. Through the transmitting antenna to he underground media launch of the high-frequency electromagnetic pulse, acquisition and use of reception antenna medium dielectric constant reflection back decomposition of the lector-magnetic wave, the medium as a means of internal anomaly detection. And resistivity, low-frequency electromagnetic induction law and seismic and other conventional detection of underground non-destructive methods, a geological radar speed detection, detection process of continuous, high resolution, easy to operate a flexible, low-cost exploration, detecting a wide range of (to Detection of metal and non-metallic), and other advantages.Therefore, ground penetrating radar in recent years has been the focus of international academic and remote sensing technology has become an important branch. Although the geological radar in the design and realization of a very complex, but its national defense, public security, urban construction, highways, railways, airports, water conservancy, transport, mines, tunnels, archaeology and many other fields have shown a strong vitality and broad prospects. Therefore, ground penetrating radar technology related to research on the development of the national economy is of great significance.This paper describes geological history and development of radar of the status quo, discusses the radar in geological prospecting works in the application and in-depth study and explores the geological radar data processing technology to compare a variety of digital processing methods, summed up the various methods of Advantages and disadvantages and applicability conditions.One-dimensional filtering and two-dimensional filtering method now widely used in seismic data processing, these methods of geological radar data of the same digital processing have a good effect, the paper filter on these principles, and other commonly used methods and gives a systematic exposition, And pointed out the advantages and disadvantages of various methods of processing the application.Geological radar in the construction process, often encountered from the ground floor of the multiple ground and ground penetrating radar data processing, interpretation and exploration projects in the application of the interference, these multiple serious impact on the profile of data quality and noise letter. In addition, the amount of data collected are often larger, the paper predicted by deconvolution methods efficient, economic solution of this issue. The better balance happens between speed and efficient.In recent years, people resume signal analysis methods and offset seismic imaging technology applied to the data processing and interpretation, and has achieved good results. In this paper, these methods will be applied to the geological information of the radar data processing and interpretation process, discusses in detail the principles of these methods, the algorithm. This article will offset Kirchhoff integral by the introduction of ground penetrating radar data migration, but the geological characteristics of the radar itself, it will be specifically for the development of geological radar imaging method of migration.In geological radar data interpretation process faces a wave and the wave interference identification of problems. In this paper, the identification of interference wave does a detailed introduction. On the ground floor of different media reflected wave different set of identifying characteristics of a detailed exposition, and will wave the group to identify ways to sum up three points. On the ground floor of a typical target group-specific features introduced. Furthermore, signal analysis of complex geological radar data interpretation in the application was discussed. In this paper, water and land two examples of exploration projects. Through the test of practice, address the special needs of exploration projects, to meet the geological prospecting works in the course of the radar all the technical requirements under the premise of the choice of targeted low-frequency antenna, a reasonable choice of processing and handling methods, the method can be Effective to achieve the purpose of exploration projects, solve practical problems encountered in the works.Finally, the ground penetrating radar technology limitations were discussed, and the prospects for the development of methods and the direction in light of its own needs were discussed. For the current interpretation of the much-needed software and digital processing technology, elaborated on the author's point of view, these technologies may not immediately get, but these...
