Abstract

Abstract

A model of random panicles constructed by the operation of self-similarity in fractal geometry is presented, and the correlation function of its number density is obtained. The model, which can be constructed with a definite method, has the characteristic of self-similarity in structure, and its correlation functions can be obtained accordingly. Therefore, it can be used conveniently in theoretical study and digital simulations of wave interaction in random media. As an example, this model has been applied to analyse the range dependence of volume scattering in radar echoes. The results agree well with Rastogi's (1990) simulation results.
