Where to find the phased.URA steering vector equation
24 views (last 30 days)
after defined URA using phased.URA, using phased.SteeringVector, I can get the URA steering vector. 1. where I can find the math equation behind phased.SteeringVector function? 2. if I have a 5x5 URA, the phased.SteeringVector gives a 25-element vector of the URA, how do I link the elements in the vector to the elements in the URA, or how do I build a 5x5 matrix, its elements match 5x5 URA elements?

You can find the general equation here at
There is a one to one mapping between the elements and weights. For URA, I think the index follows the MATLAB convention of matrix indexing. You can confirm this by using viewArray and turn on ShowIndex parameter.
