This paper presents the study of microwave signal attenuation on oil palm trees at 0.9 GHz,
1.8 GHz and 2.3 GHz frequencies. The main objective is to investigate the characteristics of …

An improved spectral coefficient method based on Chebyshev polynomials of the second
kind is employed to solve the vector radiative transfer (VRT) equation under the assumption …

The propagation loss in mixed‐path mobile communication was calculated using parabolic
equation (PE) method. The implicit finite differences scheme of the Crank–Nicolson method …

In this paper the formalism of Parabolic Equations for narrow angles, a statistical method, the
Moving Average and a empirical model, the Hata-Davidson, were used for to study on the …

An analysis of laser backscattering enhancement is pursued to probe the parameters that
affect a laser radar cross-section (LRCS) measurement. The performance of backscattering …

A high frequency theoretical model of propagation and scattering in vegetation is presented
which uses scalar radiative transport theory. The specific problem analyzed is that of a …

Neste trabalho é calculada a perda de propagação em um ambiente misto (floresta, ruas e
edificações) utilizando-se o método de equações parabólicas com a adição de uma variável …

The accuracy of radar detection is measured in this paper through comparing the laser radar
cross-section (LRCS) to RCS data for plane-wave incidence in free space. This is to study …

Representing an accurate model of how pulse waves are propagated and scattered in the
vegetation is an interest in the area of wireless communications. Several research projects …
