Estimation of Q: a comparison of different computational methods

Peng Cheng, Gary F. Margrave

In this article, four methods of Q estimation are investigated: the spectral-ratio method, a match-technique method, a spectrum modeling method and a time-domain match-filter method. Their accuracy and the reliability of Q estimation is evaluated using synthetic data. Testing results demonstrate that the time-domain match-filter method is more robust to noise and more suitable for application to reflection data than the other three methods.
