# steervec

Steering vector

## Description

returns
the steering vector `sv`

= steervec(`pos`

,`ang`

)`sv`

for each incoming plane
wave or set of plane waves impinging on a sensor array. The steering
vector represents the set of phase-delays for an incoming wave at
each sensor element. The `pos`

argument specifies
the positions of the sensor array elements. The `ang`

argument
specifies the incoming wave arrival directions in terms of azimuth
and elevation angles. 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`

.
All elements in the sensor array are assumed to be isotropic.
