摘要：

This paper proposed and demonstrated an improved wavelet transform modulus maxima (WTMM) denoising method to decrease the temperature error without decreasing spatial resolution in Raman distributed temperature sensors. In this scheme, the WTMM were obtained by combining those on the high and low decomposition scales, and the temperature signal was reconstructed using the WTMM. Experimental results show that the new proposed method has better denosing effect than the conventional one, allowing for the temperature error reduction of similar to 2 degrees C at 30 degrees C and 60 degrees C without decreasing spatial resolution comparing to original data.
