caculate the dielectrics of rough surface ,especially the soil
This directory contains MATLAB functions for a simple model of GPR performance
that takes into account soil texture and water content in predicting
attenuation and reflection losses for a GPR target (such as a landmine)
buried in an homogeneous soil.

The model is described in

B. Borchers, J. M. H. Hendrickx, B. S. Das, and S. H. Hong, "Enhancing
Dielectric Contrast Between Land Mines and the Soil Environment by
Watering: Modeling, Design, and Experimental Results", in Detection
and Remediation Technologies for Mines and Minelike Targets V,

The MATLAB functions are:

alpha Computes the attenuation coefficient alpha
loss Computes reflection+attenuation losses
myeps Computes the complex dielectric constant of the soil
calls "higheps" or "loweps" depending on the
frequency range. We don't use "eps", because there's
a built-in MATLAB function with the name "eps"
ploteps Plot the dielectric constant for a sample soil.
plotloss Plots the attenuation/reflection losses for the
sample soil.
reflect Computes reflection losses.

To see a quick example of what the package can do, simply type the
command "plotleps" at the MATLAB command prompt. This will show you
the predicted real and imaginary parts of the dielectric constant
for a particular soil from the paper. Then type "plotloss" at the
MATLAB command plot. This will show you predictions of the signal
attenuation and reflection losses associated with this soil for a
mine buried at 15cm depth.

System Requirements:

No special requirements.
Program Release Status: New Release
Program Install Support: Install and Uninstall
