Pick up weak signal information of San Xing Dui archaic relic using remote sensing technique

摘要

This article gives a concept about weak signal information of archaic relic with the help of remote sensing technique, and summarizes some main methods of that. Taking Sanxingdui site for example, we execute serials of image interpretation to summarize weak signal information about archaic relic. We have made some important progress in understanding of the old Sanxingdui city, at the same time we think Sanxingdui has two cities, one is outside city, and the other is inside city.
