Title
The optimal focusing subspace for coherent signal subspace processing
Abstract
We introduce a technique to determine an optimal focusing frequency for the direction-of-arrival estimation of wideband signals using the coherent signal-subspace processing method. We minimize the subspace fitting error to select an optimal focusing frequency. Direct optimization of this criterion can be computationally complex-the complexity increases with the number of frequency samples. An alt...
