Abstract
Directional scanning measurement is the dominant
strategy taken to measure channel spatial profiles for millimeter
wave (mmWave) frequency bands. The focus of the
paper is on wideband channel spatial profile reconstruction
and angular sampling interval (ASI) selection for directional
scanning measurement. We propose to employ the trigonometric
interpolation technique to reconstruct the spatial channel profile
and to use Nyquist sampling theorem and spherical wave mode
theory to determine the ASI. Our analysis demonstrated that
the half-power beam width (HPBW) of the antenna is a good
approximation for the ASI setting to ensure accurate directional
scanning measurements. The reconstructed power-angle-delay
profile (PADP), composite power angular spectrum (PAS), delay
and angle characteristics match well with those of the target in
the measured data when the ASI is set to the antenna HPBW.
