Conversion Of Hydraulic Conductivity To Synthetic Radar Traces

In the interest of interpreting radar data and establishing a empirical correspondence between<br>hydraulic conductivity and ground penetrating radar data, hydraulic conductivity logs have<br>been converted to synthetic radar traces. The assumption in the computation is that hydraulic<br>conductivity is closely related to porosity and thus water content and dielectric constant.<br>The synthetic radar traces have been used to interpret the radar cross section in terms of<br>zones of hydraulic conductivity.<br>In the absence of a deterministic model between radar waveforms and hydraulic conductivity<br>empirical relations are sought. Radar data have been acquired at the MADE site near Columbus,<br>Mississippi. Hydraulic conductivities measured in wells have been converted to dielectric<br>constant using a simple empirical relationship and used to compute the radar traces that<br>would be obtained at the borehole. The comparisons with the field radar traces are encouraging.<br>Key words: radar, hydraulic conductivity, synthetic radargram
