基于FPGA的声呐信号数字预处理机的设计
Digital Sonar signal Preprocessor Based on FPGA
摘要
Abstract
In this paper ,a digital sonar signal preprocessor based on FPGA is designed .The system completes the task of synchronous sampling of 30-channel signal from the sensors ,quadrature demodulation FIR filtering and beamforming can be done in order to reduce the calculation pressure of upper monitor .This sonar signal sampling and preprocessing system balance the speed of sonar signal sampling and processing .关键词
