摘要

蒸发风道是影响近海面无线电波传播的重要因素。基于大气边界湍流理论和抛物波动方程，提出了考虑随机折射率的传播模型。数值模拟比较了湍流的影响，结果表明大气湍流的物理机制是一个重要的考虑因素。它可以减小雷达波的传播距离，影响雷达对地平线以外目标的探测概率和探测距离。

Parabolic-equation based study of atmospheric turbulent effects on evaporation duct radio wave propagation

Evaporation duct is an imporatn factor affecting the near sea surface radio wave propgation. Based on the atmospheric boundary turbulence theory and the parabolic wave equation, the propagation model considing the randomized refractivity is proposed. The numerical simulation compared the influence of theturbulence the results shaows that accounting for the physical mechanism of the atmosphere turbulence is s an important factor. It can reduce the propagation distance of radar wave propagation and affect the detection probability and range of radar to the tarbet beyond the horizon.
