Backscattering Coefficient (bb)

The backscattering, or backward scattering, coefficient, in units of m-1.  It indicates the attenuation caused by scattering at angles from 90 to 180.  bb is commonly estimated from measurements of the VSF around a single fixed angle.  See Determining bb with Fixed-Angle Sensors for details.


It is one of several coefficients derived from the Volume Scattering Function, each quantifying the total scattering within a particular range of angles.  The most commonly seen is b, the total scattering coefficient.  bf is the forward-scattering equivalent of bb, indicating scattering in the range of 0 to 90.
