| Abstract: | 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. |
