“…From [15]- [18], Bourlier et al [11] evaluated the scalar Green's function for a homogeneous medium overlying a duct (medium ) with a linear-square refractive index profile (the rough surface was not considered). From the boundary conditions, the exact spectral Green's function is derived with the help of Airy functions.…”

For a two-dimensional problem and at microwave radar frequencies, this paper presents a method to compute the field scattered by a highly conducting (the impedance boundary condition is applied) rough sea surface in the presence of a duct having a linear-square refractive index profile below a medium of constant refractive index. In a previous paper, the corresponding Green's function, which allows us to solve the propagation problem, has been derived without considering the sea surface. Using the boundary integral equation (BIE) method, this paper solves jointly the scattering problem from the sea surface and the propagation problem by including this Green's function in the BIE. In addition, to efficiently solve the linear system obtained from the method of moments by discretizing the integral equations, the forward-backward method is applied, which allows us to consider very long rough surfaces.

“…EVD has a nearly permanent presence in the subtropical regions of the Pacific Ocean [2]. After analyzing the marine observation data from 1982 to 1999, Lin [3] concluded that the occurrence probability of EVD was more than 85% over the sea area ranging from latitude 0°N to 40°N and longitude 100°E to 140°E.…”

The distance of conventional X-band microwave propagation over the sea surface is within 'radio line-of-sight' (RLOS) which limits its application in long-range land-buoy communication. To overcome the above limitation, evaporation duct (EVD) is employed as an alternative to the physical channel in the land-buoy communication and the corresponding communication distance could be extended to hundreds of kilometers. To explore the effects of EVD channels on communication signaling, an over-the-sea trans-horizon propagation experiment was conducted in the northern part of the South China Sea. The statistical features of the received signal level (RSL), e.g. median, fading range, and probability density function (PDF), are reported. Moreover, the influence of sea surface wind speed and the height of the receiving terminals on RSL fluctuation are also discussed. Finally, Some conclusions are given.

“…The effects of air turbulence has been studied by applying a perturbation technique in a mode theory [12], or applying a phase-screen method in an SSF model [13,14]. The results of different models have been compared over a series of over-water measurements, in a nearly standard atmosphere [14].…”

Abstract-The split-step Fourier (SSF) algorithm is applied to simulate the propagation of radio waves in an atmospheric duct. The refractive-index fluctuation in the ducts is assumed to follow a twodimensional Kolmogorov power spectrum, which is derived from its three-dimensional counterpart via the Wiener-Khinchin theorem. The measured profiles of temperature, humidity and wind speed in the Gulf area on April 28, 1996, are used to derive the average refractive index and the scaling parameters in order to estimate the outer scale and the structure constant of turbulence in the atmospheric boundary layer (ABL). Simulation results show significant turbulence effects above sea in daytime, under stable conditions, which are attributed to the presence of atmospheric ducts. Weak turbulence effects are observed over lands in daytime, under unstable conditions, in which the high surface temperature prevents the formation of ducts.
