Multiple Scattering Effects in Pulsed Radar Systems: An Intercomparison Study

Battaglia, A., S. Kobayashi, S. Tanelli, C. Simmer, and E. Im (2008), Multiple Scattering Effects in Pulsed Radar Systems: An Intercomparison Study, J. Atmos. Oceanic Technol., 25, 1556-1567, doi:10.1175/2008JTECHA1023.1.
Abstract: 

In this paper, two different numerical methods capable of computing multiple scattering effects in pulsed-radar systems are compared. Both methods are based on the solution of the time-dependent vectorial form of the radiative transfer equation: one exploits the successive order of scattering approximation, the other a forward Monte Carlo technique.

Different benchmark results are presented (including layers of monodisperse spherical water and ice particles), which are of specific interest for W-band spaceborne cloud radars such as CloudSat’s or EarthCARE’s cloud profiling radars. Results demonstrate a good agreement between the two methods. The pros and cons of the two models are discussed, with a particular focus on the validity of the second order of scattering approximation.
