The summary of the surface ground penetrating radar applied in subsurface investigation
探地雷达应用概述

The method of sarface ground penetrating radar(GPR) applied in subsurface investigattion are systemic summarized based on ASTM standard guide.It indudes the oart terminology;the relationship between penetration depth of radar and central frequency,vertical resolution and lateral resolution;the selection of approach in the field procedures;the methool for estimating propagation velocity and velocity sounding;data display and inter pretation methodsfor the assessment of subsurface materials.An overview of the impulse GPR methad is prouided in the paper and GPR measurements as described in the paper are used in geologic,engineering,hydrologic and envirmental application.Since up to now,there isn't any national or vocational standard guide on GPR,the paper can be reference for GPR application and preparation for GPR guode.
