    针对多波束测深系统中高分辨海底地形探测问题,提出一种基于多子阵波束域MUSIC算法(Multiple sub-array beam space MUSIC,MSB-MUSIC),它将多子阵波束域算法的稳健性与MUSIC算法的高分辨特性相结合,从而实现高分辨海底地形探测算法.同时针对高分辨算法运算量大难以实时实现的问题,设计了由6片DSP和2片FPGA(现场可编程门阵列)组成的并行处理系统用于算法的实时实现.海底仿真场景和湖上试验都验证了算法的有效性.

    Aiming at the problem of high resolution seabed terrain detection using multi-beam bathymetry system, a method of multiple sub-array space MUSIC (MSB-MUSIC) was proposed. This method combines the robustness of beam-forming and the high resolution character of space modeling, so it can be used to effectively implement high resolution seabed terrain detection. At the same time, to solve the problem of huge computation load, a parallel processing platform using 6 DSPs and 2 FPGAs was designed to implement the algorithm. Both seabed simulation and lake test prove the validity of the method.
