N2 - When modeling the volume power spectrum for a collection of randomly positioned scatterers in an impedance map, the assumption is usually made that the incoherent component of the spectrum is much larger than the coherent component. With this assumption, scattering form-factor models such as the Gaussian, fluid-filled sphere, etc. can be fitted to the impedance map volume power spectrum for the purpose of estimating parameters such as the scatterer size. The accuracy of the assumption concerning incoherent and coherent component spectrum magnitudes was studied using simulated collections of spheres in a finite container.
