摘　　要：为满足相控阵三维声纳系统对可视化处理的数据实时性和完整性要求,提出一种三维声纳系统高吞吐量数据的并行处理方法。通过对声纳数据的粗粒度划分,将处理过程进行任务划分并映射到多线程,实现主控板数据处理过程的流水线作业。实验结果表明,在高吞吐量情况下,该方法能将单横截面数据从获取到网络发传完成之间的时延控制在50 ms以下。In order to meet the demands of data real-time and integrity for visualization processing of 3D phased-array sonar,this paper proposes a parallel processing method for high throughput data processing.This method divides sonar data into pieces to make process into tasks which are mapped to multi-thread,in further to implement parallel pipeline of total data process on sonar main control board.Experimental result shows that this method can make the delay of single layer processing less than 50 ms under high amount throughput.
