What noise floor is used during processing in SeaReport?
The noise floor, together with returned signal strength, is used to calculate SNR. The instrument noise floor is unique for each instrument and deployment. During processing in SeaReport the specific noise floor is not known, hence the following values are used as input for all instruments:
|
Instrument frequency |
Noise floor (counts) |
|
2 MHz |
20 |
|
1 MHz |
20 |
|
600 kHz |
30 |
|
400 kHz |

|
470 kHz |
