水下目标定位系统的信号处理模块设计

摘要

针对水下目标的主被动定位功能需求和具体的技术指标要求,结合数字信号处理器(DSP)和现场可鳊程门阵列(VPGA)的各自优势,设计了基于DSP及FPGA的数字信号处理模块,以此处理模块为硬件平台,编程实现了相应的时延估计应用程序,并进行了实验验证,实验结果表明此信号处理系统时延估计精度高,满足了目标定位的要求.%Aiming at the requirements of initiative and passive locating function and specific qualification needs, combing the advantages of DSP and FPGA, a digital signal processing module was designed, it used this processing module as the hardware platform, and realized corresponding time delay estimation application program, through an experiment, the results show that this signal processing system has high time delay estimation accuracy, it satisfies the demand of target locating.
