step
System object: phased.IsotropicHydrophone
Namespace: phased
Voltage sensitivity of isotropic hydrophone
Syntax
resp = step(hydrophone,freq,ang)
Description
Note
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.
returns
the voltage sensitivity for the hydrophone at the specified operating
frequencies and in the specified directions of arriving signals.resp
= step(hydrophone
,freq
,ang
)
Note
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
call the release
method to unlock the object.

Algorithms
The total sensitivity of a hydrophone is a combination of its
frequency sensitivity and spatial sensitivity. phased.IsotropicHydrophone
calculates
both sensitivities using nearest neighbor interpolation, and then
multiplies the sensitivities to form the total sensitivity.
