摘　　要：针对水声目标实测数据量庞大,LOFAR和DEMON分析计算量大的问题,设计了一个基于Visual C++6.0的数据库管理系统。管理系统通过ADO接口实现与SQL Server 2005数据库管理程序的数据交换,保证了数据稳定存储和高效传输。通过内存映射文件技术,实现了对大数据文件的快速读取。采用CPU与GPU并行计算进行了LOFAR和DEMON分析,实现了LOFAR和DEMON谱图的实时显示。整个数据库管理系统操作简洁高效,可靠性高,具有广泛的实际应用价值。To deal with large amount of underwater acoustic target measured data and large amount of cal- culation of LOFAR and DEMON, a database management system based on Visual C ＋＋ 6.0 was designed. The system exchanged data with SQL Sever 2005 database management program through ADO interface in order to ensure a stable storage and efficient data transmission. The system read data using memory mapping file, which can improve the efficiency of file read. The system analyzed LOFAR and DEMON using parallel computing based on CPU and GPU,which can real-timely display the spectrogram of LOFAR and DEMON. The system designed concisely, efficiently and of high reliability, which has extensive practical application value.
