摘要

本文探讨了仓鸮听觉系统的抽象模型在多大程度上可以作为数字室内定位系统的核心。第一个原型已经在低成本Altera Cyclone II现场可编程门阵列上实现。系统时钟为85 MHz，该原型在11 kHz至300 MHz的频率范围内产生约0.02 ns的分辨率。所获得的时间分辨率相当于约1mm的空间分辨率。

Precise indoor localization with low-cost field-programmable gate arrays

This paper explores to what extent an abstract model of the barn owl auditory system can be utilized as the core of a digital indoor localization system. A first prototype has been implemented on a low-cost Altera Cyclone II field-programmable gate array. With a system clock of 85 MHz, this prototype yields a resolution of about 0.02 ns for frequencies ranging from 11 kHz to up to 300 MHz. The achieved time resolution equals a spatial resolution of about 1 mm.
