Beam-blockage simulations The following slides show calculations of terrain beam-blockage for low-elevation angles The code used, developed by Steve Nesbitt and Tim Lang, follows Bech et al. (2003) and is described in Lang et al. (2009) The simulations were conducted with a ~ 1 km resolution terrain and assuming an antenna located at 10 m above ground level and a beam-width of 0.93° The blockage simulation figures have 20 km rings.
The simulation for two locations, called NPOL-loc1 and NPOL-loc7 are presented here
