| Abstract: | 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. |
