windowing a 2-d signal
i want to window this data with Hanning window.. the data is 64x64 ISAR radar's backscattered data.. when i have an image by IFFT2 .. the image has unwanted sidelobes..
so i think if i can window this data i will have a better image.. do you have any idea about that??
how can i window 2-d signal??
