Property Detail

• float carrierFrequency

  Carrier frequency (Hz).

• float noiseLevel

  Power spectral denisty of ambient noise (dB re uPa^2/Hz).

• float salinity

  Water salinity (ppt).

• float spreading

  Spreading loss factor (between 1 and 2, 1 = cylinderical, 2 = spherical).

• float temperature

  Water temperature (deg C).

• float waterDepth

  Nominal water depth (m).

Constructor Detail

• UrickAcousticModel(AbstractAcousticChannel parent)

  Creates the acoustic channel model.

Method Detail

• double getNoisePower()

  Computes total noise power in communication band.

  Returns:

  noise power in uPa^2

• double getRxPower(Reception rx)

  Computes received signal power (Urick 3rd ed, p111). Takes into account spreading loss and frequency-dependent absorption (Urick 3rd ed, p105).

  Parameters:

  rx - details of the received frame

  Returns:

  received power in uPa^2

• float getSoundSpeed()

  Computes sound speed in water (Mackenzie, JASA, 1981).

  Returns:

  sound speed in m/s
