Bandpass filter 2dFFT

Started by Ibrahim muhammed August 14, 2009
Hi there,

I have a 2d data, with space x time (longitude and time). I need to do a bandpass filter while taking windows on both dimensions. Dimension 1 is space and dimension 2 is time. For space, my window should be between 5.4 to 7, and for time is 1.5 to 4.

I started as:

dataa(:,:); %1:180 x 1:225

[Ns,Nt]=size(data);

Ts=1/4; % each unit of space is 0.25 of a degree
Tt/365.25 % each time unit is 10 days per year

So, how can I set window for the bandpass in both space and time axis?

Any idea will be greatly appreciated.

Regards,
Ibra
