Neste artigo, derivamos uma nova representação integral para a propagação de ondas terrestres sobre caminhos mistos terra-mar, aplicando o teorema integral de Helmholtz-Kirchhoff. Usando o método da fase estacionária aplicável uniformemente à medida que o ponto da fase estacionária se aproxima do ponto final da integral, derivamos a solução assintótica para os campos dispersos que consistem nos termos de difração de primeira e segunda ordem. Mostramos que a solução assintótica assim derivada concorda com a solução assintótica derivada pela aplicação do método de campo de abertura (AFM) e do método de fase estacionária. Confirmamos a validade e a utilidade da nova representação integral e sua solução assintótica comparando com o amplamente utilizado teorema do caminho misto e a medição experimental realizada na área de Kanto e na baía de Tóquio.

Abstract: In this paper, we have derived a novel integral representation for the ground wave propagation over land-to-sea mixed-paths by applying the Helmholtz-Kirchhoff integral theorem. By using the method of stationary phase applicable uniformly as the stationary phase point approaches the endpoint of the integral, we have derived the asymptotic solution for the scattered fields consisting of the first-order and the second-order diffraction terms. We show that the asymptotic solution thus derived agrees with the asymptotic solution derived by applying the aperture field method (AFM) and the method of stationary phase. We have confirmed the validity and the utility of the novel integral representation and its asymptotic solution by comparing with the widely used mixed-path theorem and the experimental measurement performed in Kanto area and Tokyo bay.

AB - In this paper, we have derived a novel integral representation for the ground wave propagation over land-to-sea mixed-paths by applying the Helmholtz-Kirchhoff integral theorem. By using the method of stationary phase applicable uniformly as the stationary phase point approaches the endpoint of the integral, we have derived the asymptotic solution for the scattered fields consisting of the first-order and the second-order diffraction terms. We show that the asymptotic solution thus derived agrees with the asymptotic solution derived by applying the aperture field method (AFM) and the method of stationary phase. We have confirmed the validity and the utility of the novel integral representation and its asymptotic solution by comparing with the widely used mixed-path theorem and the experimental measurement performed in Kanto area and Tokyo bay.
