We introduce a novel directional channel sounding
concept where we sweep a horn antenna around its phase center.
Directional channel measurements are thus carried out at a fixed
coordinate in space. To verify our concept, we conducted multicarrier
measurements with 2 GHz of measurement bandwidth.
The directional broadband channel was sampled uniformly within
a cube of three wavelengths side length. In this contribution, we
compare narrowband measurements with spatial averaging to
traditional broadband channel sounding. We saw that, spatial
filtering through directional antennas leads to a limited number
of propagation paths in the channel. We show the difference of
both approaches and explain the deviation by spatial correlation.
The spatial correlation is evaluated at several two-dimensional
slices. We observed wavelength-periodic correlations.
