volume scattering strength

8.43  volume scattering strength. Ten times the base 10 logarithm of the ratio of differential backscattering cross section per unit volume to the reciprocal of the reference distance. Unit, decibel (dB).

Annotation 1          The reference distance is one meter (1 m).

Annotation 2          The reference value for volume scattering strength is one inverse meter (1/m).
