Temperature accuracy enhancement of ROTDR by weighted nuclear norm minimization algorithm

Raman Optical Time Domain Reflectometer (ROTDR) is widely used in industrial fields because of its distributed temperature measurement characteristics. Temperature accuracy is an important parameter of the ROTDR system, and there are some ways including wavelet denoising and nonlocal mean to improve the temperature accuracy of the system. However, these methods either increase the cost of the system or suffer from the limitations of the method...
