多波束相干测深新算法及其DSP实现
Multibeam interferometric bathymetry algorithm and its algorithm implementation on DSP
多波束测深声纳对每个波束脚印内的海底回波信号进行幅度加权法或相位差法处理后仅获得一点的海底深度值，这既导致海底测量分辨率难以提高又浪费了波束脚印内很多有用的信息，为此本文提出了一种在每个波束脚印内采用相干处理以获得更高海底分辨率的新算法。在理论分析和实测数据处理证明其有效性的前提下，讨论了该算法在TI-DSP TMS320C6713开发板上实现的方法，并给出了一种基于RTDX的海底地形显示方案。
Multibeam bathymetric sonar uses WMT or phase difference method to obtain one seabed depth value in each beam footprint which not only leads to a difficulty in improvement of the seabed resolution but also wastes lots of useful information in beam footprints. For this reason, we propose a new algorithm that uses the interferometric technique in each beam footprint to improve the resolution of measurement. This paper firstly uses theoretical analysis and experimental data to verify the validity of this new algorithm. Then the method of algorithm implementation on TMS320C6713DSK is discussed and a seabed curve display method based on RTDX is presented.
