SGER: Development of Design Infrastructure for Multi-Modal, Distributed Sensing

9612522威尔逊在这项研究中，我们开发了一种新的分布式传感系统的信号处理层次和体系结构的设计框架。我们建议探索一种设计方法，将模拟VLSI用于在传感平面上定制前端信号处理，而将通用处理中心设置在传感平面之外，以执行针对更复杂特征分析的后端处理。我们寻求将这些分布式信号处理体系结构应用于分布在不同传感平面内并在不同传感平面上融合的传感器阵列。这些感测平面可以是相同类型的传感器，但放置在感测环境中的不同位置。或者，可以融合不同类型的感测平面，以便更准确地识别和确认感兴趣的对象。这种体系结构的分布式系统的应用是众多和多样的。这里提出的研究阶段并不寻求构建满足所有这些应用程序的系统，甚至也不寻求为这些应用程序的一个重要子集构建系统。相反，这项研究开发了一个框架，用于构建和测试新的体系结构，用于低成本、分布式传感系统的长期设计，这些系统具有在各种环境中处理大量传感站和感应点的能力。***

9612522 Wilson In this research, we develop a design framework of novel signal processing hierarchies and architectures for distributed sensing systems. We propose to explore a design methodology that combines analog VLSI for customizing front-end signal processing on the sensing plane with generic processing centers located off the sensing plane for performing back-end processing directed toward more complex feature analysis. We seek to apply these distributed signal processing architectures to arrays of sensors that are distributed within and fused across various sensing planes. These sensing planes may be of the same type of sensor but placed at different locations in the sensing environment. Alternatively, different types of sensing planes can be fused for more accurate recognition and confirmation of objects of interest. The applications of distributed systems of this type of architecture are numerous and diverse. The phase of research proposed here does not seek to build systems that satisfy all of these applications nor even systems for a substantial subset of these applications. Rather, this research develops a framework for building and testing novel architectures to be applied to the longer-term design of low- cost, distributed sensing systems that have the capability to process large numbers of sensing stations and sensory points in a variety of environments. ***
