摘要
针对水声基阵信号采集通道多,数据传输量大,采用基于VXI总线的商业货架仪器开发了一套32通道阵列信号采集及高速实时数据记录系统,并对采集的数据进行阵列信号处理;对该系统的硬件集成、软件设计及阵列信号处理测试程序集的开发作了介绍。该系统集成度高,具有良好的便携性和可扩展性,在水声基阵信号采集与分析中广泛应用。
Because the acquisition of the underwater acoustic array signal needs multi-channel and high-speed data throughput, a new 32-channel array signal acquisition, real-time high speed data recording and array signal processing system are developed based on VXI（VMEbus eXtensions for Instrumentation） commercial off-the-shelf equipments. The system hardware integration, software development and the test program set of array signal processing are described. Because the system has the characteristics of the high integration, excellent portability and expansibility, it is applied to the underwater acoustic array signal acquisition and processing.
