Earth Surface Bistatic Scattering Coefficient Prediction Model

About this technology

Overview

This MATLAB code package provides tools for predicting the bistatic scattering coefficients and coherent reflection coefficients for the water surfaces and land surfaces. These models can be applied at any elevation angle, except grazing incidence, and they work for frequencies between 1 and 100 GHz. For frequencies less than 1 GHz, the coherent component may be the dominant source of any interference effects, greatly simplifying the required modelling of Earth surface reflections.This MATLAB code implements internationally recognized standard Recommendation ITU-R P.2146-0. This code also conforms to established validation examples developed and approved by the International Telecommunications Union (ITU-R).Moreover, the following three analytic models which are widely used in academic literature for modelling bistatic scattering coefficients, are leveraged in the MATLAB code package:Small perturbation model (SPM);Kirchhoff approximation model (KA), andThe two scale scattering model (TSSM).
