摘　　要：EH4电磁系统要求在“远区”观测。当发—收距较小时 ,测点在人工源的低频段处于过渡带中 ,数据发生畸变 ,从而形成过渡带低谷。提出一种线性校正方法 ,可对过渡带数据进行校正。EH4 electromagnetic system requires distant observation.If the distance between transmission and reception is relatively short,the measuring points in the low frequency band of the artificial source will lie in the transitional zone,and the data will be subjected to distortion,thus forming the low valley of the transitional zone.A linear correction technique is put forward in this paper,which can be used to correct data of the transitional zone.

关 键 词：EH4电磁系统 过渡带低谷 近源效应 校正
