电波传播抛物方程模型在航空通信中的应用
Application of Wave Propagation Model Based on Parabolic Equation in Aeronautical Communication
摘要
Abstract
The parabolic equation( PE) model is used to predict the wave propagation characteristics for the demands of accuracy, timeliness and environmental complexity in aeronautical communication. The influ-ence of propagation loss on the aeronautical communication range is analyzed. The split-step Fourier trans-form( SSFT) technology is used to solve the PE,boundary shift method is used to deal with the complex ter-rain,and un-uniform grid technology is used to advance the precision of the field at any point in space. The model is applied to aeronautical communication simulations in the real terrain environment. Numerical sim-ulations demonstrate this model can predict wave propagation loss in complex environment correctly,and e-valuate the flight range,the farthest flight distance and the lowest flight height effectively in normal commu-nication.关键词
