Paper Abstract

An integral equation for the coherent field in a collection of large point scatterers is formulated. It differs from preceding development in that to good approximation all higher-order correlations between particles are included. The equation is developed from the self-consistent equations for multiple scattering from point scatterers in the "Twersky approximation," which ignores scatterings from particle 1 to particle 2 and then back to particle 1 everywhere. The four lowest-order terms in binary-correlation expansion correspond with those obuqned from Tsolakis, Besieris, and Kohler [Radio Sci. 20, 1037-1052; 1985]. Analysis of the region of validity reveals that the equation is a extension of previous work that is significant for small particles and higher densities.
