Target mean strength & characteristic strength
The target strength or acoustic size is a measure of the reflection coefficient of a sonar target. This is usually quantified as a number of negative decibels. For fish such as salmon, the target size varies with the length of the fish and a 5 cm fish could have a target strength of about -50 dB.
