Indoor Antenna Calibration with UAVs – On Time Domain Gating and the Influence of Motion

This contribution discusses the applicability of a UAV as positioning and measurement system for antenna calibration in an arbitrary indoor environment. Since such an environment – unlike an anechoic chamber bears the possibility of multiple reflections the feasibility of time domain gating network analyzer measurements is investigated for the time-variant propagation channels due to the motion of the UAV. Based on a simple simulation time domain gating model taking into account the motion of a UAV and its influence on measurement parameters in the frequency domain it is shown that the motion of the UAV can be neglected. The propagation channel can be considered basically static provided a usual hovering flight with a typical motion uncertainty, the data of which is obtained from an exemplarily flight trajectory.
