摘要: 结合上林湖区域水体电性参数测量结果,开展了探地雷达水下考古试验探索.在上林湖指定水域用机动木船承载雷达仪器和工作人员进行了水下情况调查,通过对比试验,分析了频率为100 MHz、200 MHz、400 MHz的雷达天线对不同深度水域及水底地层的反射特征,在此基础上,对探地雷达数据进行处理及解释.探地雷达探测结果清楚地显示了古水坝、窑炉遗址、陶瓷废墟、古河道和码头堤岸等多种不同的水下考古目标,并可对湖底地层中的局部隐伏异常实现高精度成像.经过潜水探摸,进一步核实了本次探地雷达的调查结果.Abstract: In this paper, based on the measurement result of water electrical parameters in Shanglinhulake, the authors conducted a Ground Penetrating Radar(GPR)experiment of underwater archaeological investigation with all instruments and workers on a wooden boat powered by a diesel engine. The contrast test shows reflection characteristics of different depths of water and the bottom layers in radar profiles obtained by 100 MHz,200 MHz and 400 MHz frequency antennas respectively. On such a basis,the authors processed and analyzed GPR data and drew the conclusion as follows:the GPR can not only clearly observe various underwater archaeological tar-gets such as an ancient dam,Yue kiln remains,ruins of ceramic,an ancient river and convex quays for cargo ship but also form images for several local anomalous bodies buried in the lakebed strata with high-resolution. Finally,all of these survey results were confirmed by diver inspection.
