Estimating the Efficiency of Hydrophones

You can use the page Messages to check the efficiency of the hydrophones.
1 Noise (dBv)
2 SNR
3 Period of data
4 ID of the
sensor
5 Hydrophone
You will have better performance with the following levels:
• Active wideband hydrophone with high/low gain: below -100 dBV
• Active narrowband: NC-1-04 below -80 dBV / NC-1-07 below -100 dBv
• Passive hydrophone: below -110 dBV
• SNR is correct above 20 fro PRP sensors, above 10 for NBTE sensors.
• Below these levels, SNR is low, causing a discontinuous signal
This is the interval between 2 signals that have been well received. It should
be 1 to 6 seconds for NBTE signals. For PRP signal, it should correspond to
the telegram intervals.
This is the ID of the sensor transmitting data. To know the ID of a sensor,
look at the parameter page of the sensor on the receiver page.
You can use this ID to filter the messages.
