Impulse Radar for Identification of Features in Soils

Abstract

In soils developed in loess over glacial till, the presence and depth to clay layers, or fragipans, and other features are identified with radar. Radar evaluation of depths to soil features compares well with the soil pit and core descriptions by traditional methods. Regressions of radar‐derived, actual depths of soil features are used to calibrate radar measurements. The calibration approach is verified by evaluation of radar depths and actual depths of soil features in five cores taken on the same transect, away from the pits. Radar measurements of depths to features in soils have several practical applications.
