Validation of ITU-R P.833-9 tree attenuation model for Land Mobile Satellite propagation channel at Ku/Ka band

This paper presents a comparison between Rec. ITU-R P.833-9 ("slant path" section), versus measurements acquired by CNES and NICT at 20 and 18 GHz. Although several comparisons to measurements have been done between 1 and 3 GHz in previous works, we show here also a good agreement between Rec. ITU-R P.833-9 and the measurements at Ka band for satellite propagation channel, without excessive model tuning. The demonstration is done on isolated trees and long wooden road with an innovating fitting process.
