TAU = step(H,ANG) returns
the delay TAU of each element relative to the
array's phase center for the signal incident directions specified
by ANG.

Note:H specifies the System object™ on which
to run this step method.

The object performs an initialization the first time the step method
is executed. This initialization locks nontunable
properties and input specifications, such as dimensions, complexity,
and data type of the input data. If you change a nontunable property
or an input specification, the System object issues an error.
To change nontunable properties or inputs, you must first call the release method
to unlock the object.

Input Arguments

H

Element delay object.

ANG

Signal incident directions in degrees. ANG can
be either a 2-by-M matrix or a row vector of length M.

If ANG is a 2-by-M matrix, each column
of the matrix specifies the direction in the form [azimuth; elevation].
The azimuth angle must be between –180 and 180 degrees, inclusive.
The elevation angle must be between –90 and 90 degrees, inclusive.

If ANG is a row vector of length M, each
element specifies a direction's azimuth angle. In this case,
the corresponding elevation angle is assumed to be 0.

Output Arguments

TAU

Delay in seconds.TAU is an N-by-M matrix,
where N is the number of elements in the array. Each column of TAU contains
the delays of the array elements for the corresponding direction specified
in ANG.
