Spherical_Backscattering_Analyser ComponentSpherical backscattering analyser with variable reflectivity, and mosaic gaussian response. Based on earlier developments by Miguel A. Gonzalez 2000, Tilo Seydel 2007, Henrik Jacobsen 2011. Example: COMPONENT doppler = Spherical_Backscattering_Analyser( xmin=0, xmax=0, ymin=0, ymax=0, mosaic=21.0, dspread=0.00035, Q=2.003886241, DM=0, radius=2.5, f_doppler=0, A_doppler=0, R0=1, debug=0)
