What Can We Do with a Model of the Multiples
ثبت نشده
چکیده
A very popular and effective way of removing multiples is by creating a multiple model (Verschuur et al., 1992) and using it in order to perform the attenuation of the multiples. From this multiple model, two different strategies are possible. A first strategy might consist in subtracting this model from the data. A second strategy might consist in using this model as an estimate of the noise multivariate spectrum for a pattern-like attenuation of the multiples (Brown and Clapp, 2000). This multivariate spectrum can be reliably estimated with non-stationary prediction-error filters. The first strategy is often referred as adaptive subtraction of the noise. The second is often called pattern-based method.
