| Abstract: |
| Superconducting quantum interference device (SQUID), with the advantages of ultra-high sensitivity, low noise, broad frequency bandwidth, and excellent low-frequency response, is widely used in several geophysical methods, such as vector magnetic survey, electromagnetic method, gravity and gravity gradient measurement. In this paper, the latest technological progress of SQUID and SQUID-based geophysical precision measurement technology are described. In addition, the advantages, characteristics, and existing problems of each measurement technology are analyzed. Combined with the requirements of current geophysical technology, the future application prospect is discussed and development suggestions are given. |
