where z=r/r n ，a1 is the transducer radius and λ is the wavelength.
When the concentration is low, the scattering attenuation a can be ignored, the psi=1 is calculated under the far field condition, and the suspended sediment concentration of the water body is calculated, wherein the suspended particle concentration is as follows:
at high concentration, far field, the scattering attenuation as is not negligible, where as is a function of the concentration M (r):
since there is an unknown M (r) on both sides, it is necessary to solve by iterative calculation layer by layer, for which inversion is performed using multi-frequency acoustic signals:
