利用甚低频(VLF)雷达信号研究地壳上部几百米深的地层导电率的横向变化已有几十年的时间。在航空测量中,通常是利用一个发射器或二个发射器的总磁场进行成图,它给出的基本上是平行或准平行于发射方向的导电率结构。本文提出了一种甚低频张量技术,它利用预先定义的频带中的所有有
The use of very low frequency (VLF) radar signals to study lateral changes in conductivity of formations several hundred meters above the crust has been around for decades. In aeronautical surveys, the total magnetic field of a transmitter or two transmitters is usually used to map, which gives a conductivity structure that is essentially parallel or quasi-parallel to the direction of emission. This paper presents a very low frequency tensor technique that utilizes all of the predefined frequency bands
