The baptism (El-Maghtas) site is located to the north of the Dead Sea on the eastern bank of the Jordan River. Previous archeological excavations in the surrounding area have uncovered artifacts that include the location that was home to “John the Baptist”, who lived and preached in the early 1st Century AD and is known for baptizing Jesus. Archeological excavations have revealed walls, antiquities, and ancient water systems that include conduits, pools, and ancient pottery pipes. A ground-penetrating radar (GPR) survey was carried out at select locations along parallel profiles using a subsurface interface radar system (Geophysical Survey Systems Inc. SIRvoyer-20) with 400 MHz or 900 MHz mono-static shielded antennas in order to locate archeological materials at shallow depths. The GPR profiles revealed multiple subsurface anomalies across the study area. At the John the Baptist Church site a buried wall was detected along the profiles, and at the pool site the survey delineated several buried channels. GPR data also confirmed the extension of an ancient pottery pipe at the Elijah's Hill site through the production of a clear diffraction hyperbola anomaly related to the ancient pottery pipe that could be discriminated from the 2D profiles. The GPR data were displaced using 3D imaging to define the horizontal and vertical extent of the pipe.

约旦洗礼（El-Maghtas）现场的穿透地下雷达历史结构检查

洗礼场所（El-Maghtas）位于约旦河东岸死海北部。周围地区以前的考古发掘工作中发现了文物，其中包括“施洗约翰”的住所，他于公元一世纪初生活和宣讲并以耶稣受洗而闻名。考古发掘发现墙壁，古物和古老的水系统，包括管道，水池和古老的陶制管道。使用带有400 MHz或900 MHz单静态屏蔽天线的地下界面雷达系统（Geophysical Survey Systems Inc. SIRvoyer-20）在平行剖面的选定位置进行了探地雷达（GPR）测量，以便确定考古位置浅深度的材料。GPR剖面揭示了整个研究区域内的多个地下异常。在施洗约翰教堂遗址上，沿剖面检测到一堵埋墙，在水池遗址，调查划定了数条埋藏的河道。GPR数据还通过产生与古代陶器有关的清晰衍射双曲线异常，证实了伊莱贾山丘遗址上的古代陶器的延伸，该异常可以从2D轮廓中区分出来。使用3D成像来置换GPR数据，以定义管道的水平和垂直范围。通过产生与古代陶器有关的清晰的衍射双曲线异常，可以从2D轮廓中辨别出希尔斯山的位置。使用3D成像来置换GPR数据，以定义管道的水平和垂直范围。通过产生与古代陶器有关的清晰的衍射双曲线异常，可以从2D轮廓中辨别出希尔斯山的位置。使用3D成像来置换GPR数据，以定义管道的水平和垂直范围。
