Beam Blockage Fraction (BBF) at different range and altitude. The upper row shows the digital terrain model, and the beam blockage percentage for the scans at 0, 1 and 2 degrees of elevation. The blue, green and red segments at 13 degrees azimuth on the maps (above) correspond to the cross section lines shown in the lower plot. The dashed lines represent the Beam Blockage Fraction (BBF) for each elevation at a given range.
