中文摘要：
该系统采用基于CUDA（Compute Unified Device Architecture,统一计算设备架构）并行编程模型的GPU（Graphic Pro-cessing Unit,图形处理器）,实现了整个主动声纳宽带信号处理系统的实时性。实验结果表明：该系统与CPU平台相比,处理速度提高了近一个数量级;与具有同等处理速度的DSP阵列信号处理平台相比,克服了开发周期长、成本高和移植性差等缺点。
英文摘要：
This system implements the signal processing of broadband active sonar using GPU via CUDA,and achieves the timeliness of the whole processing system.Experimentations show that it improves about one magnitude compared with CPU;Meanwhile,it has many advantages compared with DSP platform which has the same processing speed,such as shorter development period,lower cost,higher reliability and so on.
