The collection process depends on the Wavefront
property
of H
, as follows:
If Wavefront
has the value 'Plane'
,
each collecting element collects all the far field signals in X
.
Each column of Y
contains the output of the corresponding
element in response to all the signals in X
.
If Wavefront
has the value 'Unspecified'
,
each collecting element collects only one impinging signal from X
.
Each column of Y
contains the output of the corresponding
element in response to the corresponding column of X
.
The 'Unspecified'
option is available when the Sensor
property
of H
does not contain subarrays.

Vector of weights. Default:  

Subarray steering angle, specified as a length2 column vector. The vector has the form [azimuth; elevation], in degrees. The azimuth angle must be between –180 and 180 degrees, inclusive. The elevation angle must be between –90 and 90 degrees, inclusive.

collects
each channel independently.
