摘要

针对传统分布式温度传感系统的信噪比差问题，提出了利用格雷互补相关序列代替传统单脉冲实现的方案。理论分析表明，采用该技术能有效提高信噪比。最后利用MATLAB进行了仿真验证。

Abstract

The value of signa1 noise ratio（SNR）is very 1ow in conventiona1 OTDR. The employed Golay complementary sequence was proposed instead of single pulse to solve that problem. By theoretica1 analysis and simulation demonstration，it was verified that this method could effectively increase the SNR.
