RNA aka Random Noise Attenuation. The module name itself tells us that it is used to attenuate the random noise. Random noise is not linear and incoherent in nature.
Module name RNA (Random Noise Attenuation)
RNA can be used on Prestack data i.e. Shot/Receiver/CMP domain. It can also be applied on Post stack.
Horizontal sliding window Provide the number of traces to design the filter operation in the horizontal sliding window
Number of Eigen values The lower the Eigen value the harsher the noise attenuation.
