Forward Modeling of the Internal Layers in Radio Echo Sounding Using Electrical and Density Measurements from Ice Cores
Read more of: Forward Modeling of the Internal Layers in Radio Echo Sounding Using Electrical and Density Measurements from Ice CoresThe measured density and conductivity of a 181 m ice core are used to calculate a profile of complex reflection coefficients. It is confirmed that the amplitude reflection coefficients due […]
