Polarimetric bistatic radar scattering behavior of the ocean surface
this paper points out the frequency dependence on the polarimetric radar scattering behavior of the ocean surface in the frequency range 1-18 GHz (Lto Ku-band). We treat this problem with a unifying scattering model named Small Slope Approximation (SSA) to evaluate the Normalized Radar Cross Section (NRCS). The calculations were made by assuming the surface-height spectrum of Elfouhaily et al f...
متن کاملBistatic Scattering from an Anisotropic Rough Surface in Water Tank
The objective of this work was to study the scattering strength depending on the receiver and sound source positions compared to an anisotropic surface. Roughness scattering by an anisotropic rough surface was studied under controlled laboratory conditions at a frequency of 500kHz. Two kinds of anisotropic rough surfaces were used, both with a height of 3mm, but one with a wavelength of 2.5cm t...
متن کاملSoil Moisture Retrieval Using Data Cube Representation of Radar Scattering
A time-series algorithm is proposed to retrieve surface (from surface down to 1 m depth) soil moisture using the simulated radar data. The time-series approach uses co-polarized (V V and HH) backscattering coefficient (σ) values. Temporal averaging is applied to reduce the radar measurement noise. To the extent that the surface roughness does not change within the time-series window, the reduct...

متن کاملBistatic Electromagnetic Scattering from Randomly Rough Surfaces
In this paper we propose a bistatic model for electromagnetic scattering from a Gaussian rough surface with small to moderate heights. It is based on the integral equation formulation where the spectral representations of the Green’s function and its gradient are in complete forms, a general approach similar to those used in the advanced integral equation model (AIEM) and the integral equation ...
