Output responses of subarrays
Starting in R2016b, instead of using the step
method
to perform the operation defined by the System
object™, you can
call the object with arguments, as if it were a function. For example, y
= step(obj,x)
and y = obj(x)
perform
equivalent operations.

of the subarrays in the array, at
operating frequencies specified in FREQ
and directions
specified in ANG
. The phase center of each subarray is at its
geometric center. V
is the propagation speed. The elements
within each subarray are connected to the subarray phase center using an equalpath
feed.
The object performs an initialization the first time the object is executed. This
initialization locks nontunable properties (MATLAB)
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.

Subarray element weights Subarray element weights, specified as a complexvalued N_{SE}byN matrix or 1byN cell array where N is the number of subarrays. Subarrays do not have to have the same dimensions and sizes. In this case, you specify subarray weights as

Voltage responses of the subarrays of a phased array. The output depends on whether the array supports polarization or not.
