Journal ArticleDOI
An empirical model and an inversion technique for radar scattering from bare soil surfaces
TL;DR: An inversion technique was developed for predicting the rms height of the surface and its moisture content from multipolarized radar observations, which was found to yield very good agreement with the backscattering measurements of the present study.
Journal ArticleDOI
Quantitative retrieval of soil moisture content and surface roughness from multipolarized radar observations of bare soil surfaces
TL;DR: A good agreement was observed between the values of surface parameters (the rms height s, roughness parameter ks, and the volumetric soil moisture content M/sub v/) estimated by the inversion technique and those measured in situ.
Journal ArticleDOI
Semi-empirical model of the ensemble-averaged differential Mueller matrix for microwave backscattering from bare soil surfaces
TL;DR: A semi-empirical model of the ensemble-averaged differential Mueller matrix for microwave backscattering from bare soil surfaces is presented, specifying completely the degree of correlation and the co-polarized phase-difference probability density function.
Journal ArticleDOI
Condition for precise measurement of soil surface roughness
Yisok Oh,Young Chul Kay +1 more
TL;DR: A Monte Carlo simulation concluded that, in order to measure the rms height and the correlation length with a precision of /spl plusmn/10%, the surface segment should be at least 40l long and 200l long, respectively, where l is the mean (or true) value of the surface correlation length.
Proceedings ArticleDOI
An inversion algorithm for retrieving soil moisture and surface roughness from polarimetric radar observation
TL;DR: In this article, a semi-empirical polarimetric scattering model for bare soil surfaces is constructed based on the existing theoretical models in conjunction with an extensive experimental data collected with polarIMetric scatterometer systems at microwave frequencies.
