【Abstract】 Ground Penetrating Radar(GPR)is one of the most promising surface geophysical techniques used for detecting the internal structure of the subsurface.Depending on the emission,transmission,reflection,and reception of the high frequency electromagnetic pulse,GPR can produce continuous radar profiles of the subsurface rapidly and efficiently.GPR system adopts the modular design.It can produce the high resolution radar image in the depth of 0～50 m as well as the features in a highly environment adaptable,portable,easy to operate and maintain,economical and practical way.With the radar image analysis and interpretations,the subsurface structure can be reconstructed,which can meet the demand of engineering survey and environment evolution research.It will be increasingly used in a wide variety of earth science research and engineering survey.This paper presents a series of profiles in the sandbar lagoon region along Sanya coast in the Hainan Island by using the GPR technique.Based on the field experiment,it focuses on the operative principle and detailed measurement of GPR as well as the analyzing and interpreting techniques of radar images.Case study of the field profiles shows GPR can be applied to the coast environment research successfully.更多还原
