多核DSP在无人平台探测声纳中的应用研究

在信息技术日益成熟的今天,无人平台在军事和民用领域都扮演着越来越重要的角色。水下无人航行器探测已经成为水声领域重要前沿研究方向,高速运算处理能力更是整个系统的核心。本文以多核DSP作为处理核心,提出了一个水下无人平台探测声呐架构。首先对多核DSP性能做了基本介绍,并以几种基本运算和经典波束形成算法作为例子进行了说明,通过性能测试证明了这一架构适用于水下无人平台的实时信号处理。这一多核DSP架构的设计和应用在水声领域中具有一定实用价值。

Application Research on Multicore DSP in A UUV Detecting Sonar

Unmanned vehicles are playing a more and more important role in both military and civilian uses, thanks to the development of information technology. Target detection with underwater unmanned vehicle (UUV) is now a thriving frontier subject, in which high operational capability is the core. An underwater acoustic signal processing system based on multicore DSP was presented in this paper. Firstly we introduced some basic characteristics of multicore DSP by gaving some examples on basic operations and the beamforming algorithm. Then a capacity test was taken to approve that the system is qualified to function as a real-time signal processing system in underwater unmanned vehicles. This article proved that the design and application of this multicore DSP based system is practical in underwater acoustic signal processing.
