Este artigo está preocupado com a estimativa da distância de comunicação de rádio quando tanto o transmissor quanto o receptor estão distribuídos arbitrariamente em uma superfície áspera aleatória, como deserto, terreno, superfície do mar e assim por diante. Primeiro, simulamos a propagação de ondas eletromagnéticas ao longo da superfície rugosa usando o método de traçado de raios discretos (DRTM) proposto recentemente pelos autores. Em segundo lugar, determinamos três parâmetros pelo método do gradiente conjugado (CGM) combinado com o método dos mínimos quadrados. Finalmente, derivamos uma expressão analítica que pode estimar a distância máxima de comunicação quando a potência de entrada de um transmissor e a intensidade elétrica mínima detectável de um receptor são especificadas. Supõe-se que superfícies ásperas aleatórias sejam gaussianas, lei de potência de ordem pn ou distribuições exponenciais.

Abstract: This paper is concerned with the estimation of radio communication distance when both the transmitter and receiver are arbitrarily distributed on a random rough surface such as desert, terrain, sea surface and so on. First, we simulate electromagnetic wave propagation along the rough surface by using the discrete ray tracing method (DRTM) proposed by authors recently. Second, we determine three parameters by conjugate gradient method (CGM) combined with the method of least-squares. Finally, we derive an analytical expression which can estimate the maximum communication distance when the input power of a transmitter and the minimum detectable electric intensity of a receiver are specified. Random rough surfaces are assumed to be Gaussian, pn-th order power law or exponential distributions.
