浅海信道宽带信号波形快速预报方法

随着信号处理技术的发展,对浅海信道传输特性的研究与利用日益受到重视。文章研究了浅海典型环境中水下宽带信号波形的快速数值预报方法。基于波束位移射线简正波（BDRM）理论,利用傅立叶方法求解宽带传播模型,在宽带模型计算过程中,通过宽带模型频域近似展开和模型并行化两种方式,实现快速准确的宽带信号波形预报。

A Rapid Prediction Method of Broadband Signal Waveform in Shallow Water Channel

With the development of signal process,more and more attention is paid to the transmission characteristics of the shallow water of the channel.This paper researches in a typical shallow water environment of the fast broadband waveform numcrical prediction method.Based on the theory of beam-displacement ray wave(BDRM).Fourier method has been used to solve broadband propagation medel.During the calculation process of broadband model,the approximate expansion of broadband frequency-domain model and the model o...
