FIG. 7. Left panels show estimates of soil properties from the inverse model for soil properties (IMSP) algorithm from the Mud Lake site. The bars indicate the uncertainty in the parameter estimate (i.e., ± one solution set standard deviation). Triangles indicate laboratory results (RDP is the relative dielectric permittivity). The results are invalid in the shaded regions due to rough surface scattering and equipment problems. Right panels show the actual ground penetrating radar (GPR) data, the waveform attributes, and the predicted attributes.
