Abstract

Abstract: In order to analyze channel characteristic of the unmanned aerial vehicles, according to the surrounding traits around the ground control station (GCS) and the non-omnidirectional multiple antennas system, the paper has presented and analyzed a three-dimensional geometrically-based single-bounce concentric-cylinders scattering (GBSBCCS) wideband channel model. According to the characteristic of non-isotropic scattering for the azimuth angle and asymmetrical distribution for the elevation angle, the terse joint space-time-frequency cross-correlation function is derived from the flying parameters in practice. The simplified validity and the factors of the correlation are analyzed in the simulation, and results show that the correlation scale of the space-time-frequency will be enlarged while the non-omnidirectional antennas are employed in the GCS, but the non-omnidirectional antennas used in the aircraft do not affect the correlation scale.

Key words: concentric-cylinders scattering, non-omnidirectional antenna, wideband channel model, unmanned aerial vehicles, MIMO
