Beamforming Interpolation

Dear all;

I’m working on F-k analysis (with seismic noise) using the polar plot representation
and I’d like to know if is it possible to apply interpolation between the gridded bins;
if so, may I have an example how to do it?

Thanks in advance,


Hi Esteban,

what function are you using to plot your data (I am assuming matplotlib here)? If it is pcolor() or pcolormesh(), here is a small guide on how to accomplish what you are looking for, . imshow() interpolates between gridpoints automatically, but I am not sure of its support with polar plots.

You also could increase the bin number in your calculations to achieve a better resolution? To my experience, the fk algorithm is quite fast and results can be obtained within seconds for a reasonable resolution.
