M3. UWB measurement in frequency domain using VNA E5071C and spatial grid (10 x 10 spatial positions distant 3 cm each other) for antenna positioning (May 2014). The aim of the measurement was to analyze the spatial stationarity of the intra-vehicle channel.
The aim of this measurement was to analyze the spatial stationarity of the intra-vehicle channel. The measurement setup was identical as in the case of measurements of UWB in-vehicle channel in frequency domain performed on 17 Oct and 7 Nov 2013. The RX antenna and TX antennas were placed according to Figure 1. The receiving antenna was placed at 10×10 spatial points using the polystyrene rack which ensured defined location of the antenna. The polystyrene rack utilizes a 3 cm grid distance between neighboring measurement locations. For details of the measurement campaign please refer to [1]
