System object: phased.ElementDelay
Calculate delay for elements
TAU = step(H,ANG)
Starting in R2016b, instead of using the
to perform the operation defined by the System object™, you can
call the object with arguments, as if it were a function. For example,
= step(obj,x) and
y = obj(x) perform
The object performs an initialization the first time the object 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
release method to unlock the object.
Element delay object.
Signal incident directions in degrees.
Delay in seconds.
Element Delay for Uniform Linear Array
Calculate the element delay for a uniform linear array when the input is impinging on the array from 30° azimuth and 20° elevation.
Note: This example runs only in R2016b or later. If you are using an earlier release, replace each call to the function with the equivalent
step syntax. For example, replace
array = phased.ULA('NumElements',4); delay = phased.ElementDelay('SensorArray',array); tau = delay([30;20])
tau = 4×1 10-8 × 0.1175 0.0392 -0.0392 -0.1175
