摘要
This paper makes a deep study of thin layer′s electromagnetic reflection properties in accordance with the need of actual exploration.The thin layer function is a filter for incident electromagnetic wave when the thin layer reflects electromagnetic wave.For thin layer′s type and thickness influence its filtering properties,the paper introduces Hilbert Spectrum Analysis method to recognize the thin layer by exploiting this character.The method can help improve Ground Penetrating Radar′s vertical resolution on the graded thin layer up to λ/8.This paper employs such method to make a layer recognition study on actual Ground Penetrating Radar data,by which layer recognition ability of Ground Penetrating Radar can be well improved.
