中文摘要:
      深水多波束测深系统是一种高效率、高精度和高分辨率的海洋调查勘测仪器。针对深水多波束测深系统中脉冲压缩运算量大的问题,提出了一种基于分组的脉冲压缩实时算法。该算法对需要进行脉冲压缩的波束进行分组,每个节拍只计算一组波束,可大幅减少深水多波束测深系统脉冲压缩的运算时间,节省了处理器资源。该算法已成功应用于某深水多波束测深系统,经多次海试证明,工作稳定可靠。
英文摘要:
      Deepwater multi-beam bathymetric sonar is a kind of high efficiency, high precision and highresolution ocean survey instrument. Considering large computation cost of pulse compression in deepwater multi-beam bathymetric sonar, a real-time pulse compression algorithm based on grouping was proposed. The algorithm divided beams, which need pulse compression, into groups. In each beat only one beam group was calculated. The algorithm can reduce much operation time of pulse compression and save processor resources. The algorithm has been applied in some deepwater multi-beam bathymetric sonar and proved stable and reliable in sea trial.
