Application of comprehensive geophysical exploration in the archaeology of\hidden pit outside Baling mausoleum

In the designated area of the hidden pit outside the Baling mausoleum, geological radar and high-density electrical exploration method is used to measurement. By comparing and analyzing the electrical characteristics of radar（antenna with frequency of 200 MHz） and high-density electrical method（electrode distance of 0.5 m） in the stratum of 5 m underground, the data collected from geophysical exploration are processed and interpreted. It can be seen that the comprehensive geophysical method can clearly distinguish the strata with small physical differences between the upper and lower strata of the burial site structure.
