GPR survey of different archaeological sites in China

During the last five years, I have been involved in several archaeological prospecting projects carried out in China. Both high- and low-resolution GPR systems were employed in conjunction with other geophysical techniques. We have tried GPR on different type of archaeological sites, hence the archaeological targets are different in term of depth, geometry and electrical properties. The survey strategy are also different from reconnaissance survey for unknown sites to volume mapping within known sites. This paper will introduce two typical applications, the survey strategy, instrumentation, data acquisition and processing, and merits and limitation of GPR in archaeological application are also discussed.
