Abstract 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.
