Digital Signal Processing Sonar Receiver (RXDSP)

该仪器开发项目将设计、建造和测试用于海洋科学研究应用的现代数字信号处理声纳接收器（RXDSP）。开发工作将涉及使用现代模拟-数字技术对最新可用的信号处理计算机芯片进行编程。集成的声纳接收器和发射器将结合新的声学信号处理理论来生产便携式、单板声纳处理器，可以与各种微型计算机接口。一个多频率和多换能器系统将被建立和测试。最后的开发工作将在数据分析中纳入多频反演技术。科学声纳系统将在国家科学基金会资助的研究项目中发挥重要作用。这些系统将有助于研究海洋锋面和大型湖泊的细尺度斑块，因为这些地方需要深度的高分辨率。这种将新的信号处理芯片技术和声学理论相结合的开发努力将产生具有先进功能的数字声纳系统。

This instrumentation development project will design, build, and test a modern digital signal processing sonar receiver (RXDSP) for ocean science research applications. Development work will involve programming newly available signal processing computer chips using modern analog-to-digital technology. An integrated sonar receiver and transmitter will incorporate new acoustic signal processing theory to produce a portable, single board sonar processor that can be interfaced with a variety of microcomputers. A multiple frequency and multiple transducer system will be built and tested. Final development efforts will incorporate mult-frequency inversion techniques in data analysis. Scientific sonar systems will play an important role in NSF- sponsored research projects. These systems will be useful for studying fine scale patchiness in oceanic fronts and within large lakes, where high resolution over great depths is required. This development effort to merge new signal processing chip technology and acoustic theory will result in a digital sonar system with advanced capabilities.
