Comparative Analysis and Evaluation of Common Spectrum Correction Methods

Although there are many spectrum correction theories and implementations, they are individual to specific problem and lack of a comprehensive comparison. This brings down their practical value in engineering applications. To solve this problem, we hereby establish a spectrum analysis and correction system. Each method i.e. Energy BaryCenter Method, Ratioing, Phase Difference Method, Continuous Zoom and All-Phase Spectrum Analysis. Meanwhile summarizing their accuracy, universality, practicability and window function. Then, we obtained a comprehensive assessment of all kinds of methods and created reference value for practical engineering application.
