Theory of ground-penetrating radars III [PDF]

jiip, 1998
Abstract - The governing equations are Maxwell’s. The source of the current is either j = ey δ(z − z 0)δ(x)f(t) or eϕ δ(z − z 0)δ(r − r 0)f(t) (straight wire or loop of current, f(t) is a pulse).

Ecohydrologically important subsurface structures in peatlands revealed by ground-penetrating radar and complex conductivity surveys. [PDF]

, 2008
The surface pattern of vegetation influences the composition and humification of peat laid down during the development of a bog, producing a subsurface hydrological structure that is expected to affect both the rate and pattern of water flow.
