本文介绍了一种基于超宽带脉冲在两个收发设备之间传输的精确往返飞行时间测量的测距系统。描述了两种实现设备的体系结构，称为主设备和从设备。上位机通过时间-数字转换器集成电路实现时间间隔测量功能，下位机作为脉冲中继器。这两种设备都是为低成本实现和低功耗操作而设计的。文中还给出并讨论了系统样机的一些实验结果。最后给出了一些数值模拟结果，这些结果可以解释系统观测到的测距行为中的非理想现象。
This paper presents a distance-measuring system based on the accurate round-trip time-of-flight measurement of single ultra-wideband pulses, propagating between two transceiver devices. The architectures of two realized devices, referred to as master and slave, are described. The master device implements the time-interval measuring function, by means of a time-to-digital converter integrated circuit, while the slave acts as pulse repeater. Both devices are designed for low-cost realization and low-power operations. This paper also presents and discusses some experimental results obtained from the system prototype. Finally, some numerical simulations results are shown, which could provide an explanation for the non-idealities in the observed distance-measuring behaviour of the system.
