What is the steering vector?
The steering vector, sv , is an N-by-M complex-valued matrix. In this matrix, N represents the number of element positions in the sensor array while M represents the number of incoming waves. Each column of sv contains the steering vector for the corresponding direction specified in ang .
What is steering matrix?
The steering matrix is a precise mathematical description of how the antenna array should use each individual element to select a spatial path for the transmission.
