Stochastic surface models are useful for analyzing in situ roughness profiles and synthetic aperture radar (SAR) images of geological terrain. In this paper, two different surface models are discussed: surfaces with a stationary random roughness (conventional model) and surfaces with a power-law roughness spectrum (fractal model). In the former case, it must be considered that for short profiles (L<200l/sub 0/), the measured values of rms-height s and correlation length l may be significantly…

An empirical model for polarimetric scattering as a function of s(lambda) at 35deg-60deg incidence from smooth to rugged lava surfaces is derived and compared with earlier models for backscatter from modestly rough soil surfaces.

Better Estimated IEM Input Parameters Using Random Fractal Geometry Applied on Multi-Frequency SAR Data

The random fractal geometry is implemented through the calculation of the input geometric parameters of the IEM using the power-law surface spectrum and the spectral slope, and the precision and correctness of the surface roughness estimation has been improved by up to 10%.

The potential application of fractal approach for surface roughness retrieval: A study for simulated surfaces

Natural surfaces can be modelled with fractals because fractals properly account for scale invariance and self similarity of these surfaces. The well-known measure, i.e. fractal dimension (D), is the

Improved discrimination of geological units via geomorphological classification of synthetic aperture radar images

Abstract. Geological mapping usually requires field visits, but the processing and interpretation of hyperspectral satellite images can also be very beneficial for this task. Microwave or radar

Possibilistic Soil Roughness Identification for Uncertainty Reduction on SAR-Retrieved Soil Moisture

This paper tries to independently estimate the possibility distributions for both roughness parameters on the basis of a synthetically generated roughness data set and shows that a narrower possibility distribution of the soil moisture content is obtained when the possibilistic retrieval procedure is performed based on the joint possibility distributions.

Numerical Backscattering Analysis for Rough Surfaces Including a Cloddy Structure

A new description of rough agricultural surfaces is proposed, based on a composite model, including a classical surface represented by an exponential correlation function, together with a random cloddy structure, which enables volumetric structures to be introduced over the soil's surface.

Detecting Landforms Using Quantitative Radar Roughness Characterization and Spectral Mixing Analysis

In Geomorphology the landforms delineation and delimitation are based on traditional techniques which is usually achieved by two different approaches: semantic and geometric. The semantic approach

a Comparison of Uav and Tls Data for Soil Roughness Assessment

Abstract. Soil roughness represents fine-scale surface geometry which figures in many geophysical models. While static photogrammetric techniques (terrestrial images and laser scanning) have been



Lava flow topographic measurements for radar data interpretation

Surface topography is of great importance in radar backscattering, but the quantitative interpretation of data collected in the field is still a difficult problem. We present topographic profiles at

Lava flow surface roughness and depolarized radar scattering

Surface roughness has a strong controlling influence on radar scattering and other types of remote sensing observations. We compare field measurements of surface topography and dielectric constant

A study was carried out to assess the potential of using satellite images to identify a parameter that could characterize land surface condition-i.e., soil roughness, a factor that strongly

Self‐affine (fractal) topography: Surface parameterization and radar scattering

Starting with the assumption that planetary surfaces are self-affine (fractal) over the scales applicable to radar scattering, we derive various surface parameters, e.g., rms slopes and

Condition for precise measurement of soil surface roughness

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.

The effect of inhomogeneous roughness on radar backscattering from slightly deformed sea ice

By analysing the scatterometer data over azimuth scans, it was found that the backscattering variabilities are not only due to fading but also contain a textural component.

Potential Transport of Windblown Sand: Influence of Surface Roughness and Assessment with Radar Data

The transport of windblown sand is controlled by many factors, including wind regime and sediment supply. Surface roughness at the sub-meter scale is also important because it influences both the

Condition for Precise Measurement of Soil Surface Roughness

Whereas it is well known that electromagnetic scattering by a randomly rough surface is strongly influenced by the surface-height correlation function, it is not clear as to how long a surface-height
