摘要
提出了基于声多普勒波流混合测量方法,建立了相应测量方法的数学模型,并为提高波浪方向谱的反演精度设计了新型的测波阵。利用模块化,工业化的思想设计出系统实现方案,为发射机设计了非相关和相关混合的发射测量波形,使之在较大的测量范围内能提高测量的空间分辨率。
This paper advanced the synthetic echo measuring method for the distribution of ocean current and directional spectrum of ocean wave based on the doppler. We set up the mathematics module and designed new array for accurately measuring of directional spectrum. Using the idea of module and industrialization, we designed the scheme of the system. About the transmitter,we set up the mixed signal waveform to improve spatial measuring precision.
