中文摘要:
      本文针对多波束条带测深系统,提出了一种优化的数字希尔伯特(Hilbert)变换方法,来获取幅度和相位严格平衡的正交信号。给出了理论分析过程和实时产生多路正交信号的基于流水线操作的硬件实现结构。湖上实验表明了这种方法的有效性以及工程实现的简单可靠性。
英文摘要:
      For multi-beam swath echo sounder system, an optimum digital Hilbert transforming method to obtain quadrature signals with rigid amplitude and phase balances is provided in this paper. And the basic theory and realizing hardware structure based on pipelining are described. Lake trials have shown its efficiency and engineering simplicity and reliablity.
