2D IFFT on array data to get angle of arrival

Started by Unknown March 14, 2005


Currently,I have an 10x10 array of channel impulse response data. I
need to get spatial angle of arrival,azimuth and elevation angle
image information from array data. I am currently using 2 dimensional IFFT to do transform to angular domain.
However,i am not sure how to map the data after doing 2D IFFT to get the azimuth and elevation.Any one can give me some guidance? The step i have done is as follows:

1)Get the 10x10 array data at a particular time din
2)Do 2D IFFT What is the next step?Pls anyone can advise?
