| Abstract: | The TRS performance figures were studied for a small rotary-wing UAV-based wireless station. The TRS figures of the UAV wireless station are mainly influenced by the two major factors; Antenna Placement on UAV Main Frame and Propeller Rotation. The transmitting and receiving figures of the UAV wireless station are defined by coverage due to antenna placement on the UAV mainframe and scattering figures due to backscattering from UAV propellers in A2A scenarios. The key indicator of UAV wireless station TRS figures is coverage which was explored using CST Microwave Studio simulations for different antenna placements in A2G and A2A scenarios. The influence of UAV mainframe in different antenna placement scenarios was investigated using the angular spread of the UAV wireless station coverage in the A2G region (120° southern hemisphere) and the A2A region (60° along UAV equator) for single and multiple antenna systems. The scattering figures of the UAV wireless stations were characterized at different UAV propeller orientations with respect to plane wave illumination based on simulations and measurements. The radar cross-section (backscattering from propeller) was analyzed at different frequencies and angular variation (0° to 360°) along its axis of rotation. The quasi-static propeller rotation approach was used to model the rotating propeller influence (induced periodic harmonics in the backscattered wave). The influence of the rotating propeller was also verified by conducting the measurement campaign using SDR radar - DJI Matrice 100 setup. Measurements were conducted in different near and far-fields scenarios to estimate the strength of periodic harmonic components in order to analyze their impact on the A2A communication link. |
