国外航空物探系统集成技术回顾(2015~2020)

A review of foreign system integration technologies for airborne geophysical prospecting(2015~2020)

梳理了2015~2020年之间国外主要的航空物探系统集成技术的现状和进展情况。在这一时期,一些旧的系统进行了改进,也有一些不再适合市场需要而被淘汰。新的系统集成方法不断涌现:随着修正算法的改进,磁梯度吊舱开始被广泛应用;无人机系统的飞行控制能力和负载能力显著提升,已应用于磁、电、重、伽马能谱各领域;SQUID磁张量、FTG重力张量系统先后投入了航空物探商业运行,电磁法系统的信噪比进一步提升,碘化铯晶体重新受到航空伽马能谱测量设备制造公司的青睐。作为21世纪的战略技术,这些进展值得引起我们的注意。

This paper summarizes the current status and progress of major system integration technologies for airborne geophysical prospecting used abroad from 2015 to 2020.During this period,some old systems were improved,while some became obsolete.Meanwhile,new system integration methods constantly emerged during this period.Specifically,towed birds using geomagnetic gradient began to be widely applied.At the same time,with the significant improvement of flight control and load capacity,UAVs were widely applied in magnetic,electromagnetic,gravity,and gamma-ray spectrometry fields.SQUID magnetic tensor gradiometers and FTG gravity tensor gradiometers were successively put into commercial airborne geophysical prospecting.The signal-to-noise ratio of electromagnetic systems was significantly improved,and CsI(Tl)scintillators were preferred by companies producing gamma-ray spectrometry instruments.
