用地质雷达寻找宋代钧窑遗址

LOOKING FOR RELICS OF JUN KILN OF SONG DYNASTY WITH GEORADAR

对河南神后宋代古瓷窑——钧窑采用地质雷达技术进行了尝试性的探测。雷达图象能清晰地判断出文化层和生土层,对古瓷窑床、瓷片堆积、瓷罐、料泥池也均有良好的显示,在文化层强反射的背景上出现高频小振幅的弱反射异常特征为被多次烧结的古瓷窑床,匣钵上方有不太显著的双曲线异常;瓷片堆积处以稍高的频率和稍低的反射强度为其异常特征;所发现的几处料泥池的上方均显示出同相轴一分为二的特征,其一为向上突,其二为向下倾,最后合为原同相轴方向的雷达图象。对乱石堆造成的干扰进行了讨论。

The georadar technique is experimentally used in detecting ancient Jun kiln of Song dynasty located in Shenhou town,Henan province. The clear image of cultural layer and immature layer can be obtained with georadar prospecting. The bed of ancient china kiln, china slice heap, china container and pool of material of clay are clearly displayed in the image of georadar well. On the background of strong reflections of cultural layer,the repeatedly scorched bed of ancient china kiln is represented with high frequency and weak reflection abnormality. The hyperbola arch-like abnormal character is caused by the sagger,and the abnormal character of china slice heap is represented with slightly high frequency and low strength reflection. The event is divided into two parts at some pools of material of clay. The first part is upward,the second part is downward,and finally they compose the georadar image with the same phase axis direction. The interference of confused stone heap is also discussed in this paper.
