Bandpass filter 2dFFT
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
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.
