摘要

提出了一种能够扩展动态范围的相干OFDR模型。该系统采用π/2相移技术，以获得复杂的干扰信号。对得到的复信号进行处理，去除频域的直流峰和镜像峰。仿真结果表明，动态范围得到了增强。

Simulation result for dynamic range extension in coherent optical frequency domain reflectometry

A coherent OFDR model that enables to extend the dynamic range is proposed. π/2 phase shifting technique is involved in the proposed system in order to obtain complex interference signal. The obtained complex signal is processed to remove DC and mirror peaks in the frequency domain. The simulated results show the enhancement of dynamic range.
