This paper presents an optimized Land Mobile Satellite (LMS) propagation channel model for Ku/Ka band. Here, a physical-statistical hybrid approach is proposed in order to simplify as much as possible the synthetic environment and the electromagnetic model, while keeping a good representation of the satellite propagation channel. This approach is complementary of full statistical approach [1] as a specific environment can now be tackled instead of a mixture of different propagation conditions. An original validation of the model is presented here, with an innovative method based on 360° panoramic images analysis in order to rebuild a simple synthetic environment.

“…Figure 6: CNES measurement, signal attenuation behind the treesStill from CNES measurement campaign at 20GHz[10] [11], large wooded road were extracted. Indeed, the trajectory tagged as "Sub Urban" contains large portions of roads surrounded by trees (2 x 60 km[10]). From these trajectories, it was possible to extract only the tree attenuation statistics as we use 360° images processed by a deep learning algorithms in order to automatically detect when the signal is obstructed by trees[12].…”

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.

Land Mobile Propagation Satellite Model based on 360° images

This paper presents a new concept of LandMobile Propagation Satellite model. The main idea is to predict the propagation channel based on the analysis of 360° images. To do so, concurrent RF / optic measurements have been done in the past and this paper will present the correlation study between the images and RF signal. Finally, a coupling model RF / images is proposed here, which allows a LMS channel prediction between 1 to 30 GHz.
