phased.IsotropicHydrophone
Isotropic hydrophone element
Description
Thephased.IsotropicHydrophone
System object™ models an isotropic hydrophone for sonar applications. An isotropic hydrophone has the same response in all signal directions. The response is the output voltage of the hydrophone per unit sound pressure. The response of a hydrophone is also called its sensitivity. You can specify the response using theVoltageSensitivity
property.

Creation
Description
creates an isotropic hydrophone System object,hydrophone
= phased.IsotropicHydrophonehydrophone
.
creates an Isotropic hydrophone object,hydrophone
= phased.IsotropicHydrophone(Name=Value
)hydrophone
, with each specified property set to the specified value. You can specify additional name-value pair arguments in any order as (Name1=Value1
,...,NameN=ValueN
).
Example:水听器=分阶段。IsotropicHydrophone(FrequencyRange=[0 1000],BackBaffled=true)
creates an isotropic hydrophone element with its frequency range specified between 0 and 1000 Hz.

To use an object function, specify the System object as the first input argument. For example, to release system resources of a System object namedobj
, use this syntax:

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.
