System object: phased.ArrayResponse
Package: phased
Calculate array response of sensor array
RESP = step(H,FREQ,ANG)
RESP = step(H,FREQ,ANG,WEIGHTS)
RESP = step(H,FREQ,ANG,STEERANGLE)
RESP = step(H,FREQ,ANG,WEIGHTS,STEERANGLE)
RESP = step(H,FREQ,ANG,WS)
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.

as weights applied to each element within each subarray. To
use this syntax, set the SensorArray
property to an array that
supports subarrays and set the SubarraySteering
property of the
array to 'Custom'
.
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.
