Abstract：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.
