Passive FK

Post by cecidip »

Hi,
I have acquired a data set of passive seismic with a linear array. The data consist on 10 stacks of 10s, and a geoph spacing of 3m. Though this is not the most recommended setup, for what i've read its doable.
When i try to process it with "Linear F-K for passive experiments" the curves i obtain are not reasonable. I have decreasing slowness with frequency (and this has happened to me with every linear passive dataset i tried) . Is there a special way to process this type of data ?
Thank you,
Cecilia

Can you send me your dataset? (email or any upload facility if it is too large for this forum?
