极地航空重力测量及其应用进展

PROGRESS IN APPLICATION OF AIRBORNE GRAVITY MEASUREMENTS IN POLAR REGIONS

在论述航空重力测量技术在目前重力场信息获取中不可替代性的基础上,回顾并简述了国际、国内航空重力测量技术的发展历史,介绍了航空重力测量的基本原理,总结了航空重力测量技术在极地航空地球物理勘探任务中的应用。指出航空重力测量技术是目前唯一兼顾高精度高分辨率并且能覆盖全南极区域的观测手段,在完善南极地区全球重力场模型、研究南极地区地质构造、质量变化等任务中起着非常重要的作用。

This review introduces the basic principles of airborne gravity measurements,summarizes the history of development of both international and Chinese airborne gravity measurement technology,and describes the application of airborne gravity measurement technology to airborne geophysical exploration in polar regions.It is confirmed that airborne gravity measurement technology is the only means of obtaining such high-precision high-resolution observations of the entire Antarctic area.Thus,the technology is vital to improving the global gravity field model in Antarctica,supporting research of Antarctic geological structures,and enhancing data quality.
