近年来，探地雷达(GPR)属性技术在很多方面得到了应用，但在考古领域的应用还很少。尤其是我们如何从二维或三维雷达数据中提取有效的属性，以便我们能够绘制和描述大型文化遗址中的众多考古目标？本文应用探地雷达属性技术对云南腾冲南召古堡遗址进行了调查。为了更好地对考古目标(古城墙、古窑址、古墓葬)进行分析和描述，我们对采集的探地雷达数据进行了标准化整理，并将其送入地震资料处理解释工作站。对数据进行了处理，包括各种探地雷达属性的提取、分析和优化，并结合考古钻探数据。我们选择均方根幅度、平均峰值幅度、瞬时相位和最大峰值时间来解释三个考古目标。通过对比分析，明确了不同的考古目标应该使用不同的属性来解释，地平线追踪后的属性分析结果比基于时间切片的结果要好得多。
Ground penetrating radar (GPR) attribute technology has been applied to many aspects in recent years but there are very few examples in the field of archaeology. Especially how can we extract effective attributes from the two- or three-dimensional radar data so that we can map and describe numerous archaeological targets in a large cultural site? In this paper, we applied GPR attribute technology to investigate the ancient Nanzhao castle-site in Tengchong, Yunnan Province. In order to get better archaeological target (the ancient wall, the ancient kiln site, and the ancient tomb) analysis and description, we collated the GPR data by collected standardization and then put them to the seismic data processing and interpretation workstation. The data was processed, including a variety of GPR attribute extraction, analysis, and optimization and combined with the archaeological drilling data. We choose the RMS Amplitude, Average Peak Amplitude, Instantaneous Phase, and Maximum Peak Time to interpret three archaeological targets. By comparative analysis, we have clarified that we should use different attributes to interpret different archaeological targets and the results of attribute analysis after horizon tracking is much better than the results based on a time slice.
