Computer simulation of enhanced backscattering from randomly distributed spherical scatterers at 30 GHz and comparison with measurement

This paper presents a computer simulation of backscattering enhancement from randomly distributed spherical water scatterers at 30 GHz, corresponding to laboratory measurements. Because of the finiteness in the scattering volume size, we adopt a very simple direct simulation method, together with a sampling of the scattering paths for triple scattering and higher to minimize computer time. The spherical wavefront and the directivity functions of transmitting and receiving antennas are taken into account. The simulation results agree favorably with measurements. Some of the knowledge on the detailed characteristics of enhanced backscattering is also obtained.
