| Summary: | Near-field measurements are established techniques to obtain the far-field
radiation pattern of an Antenna Under Test via near-field measurements and
subsequent near-field far-field transformation. For measurements acquired in
echoic environments, additional post-processing is required to eliminate the
effects of multipath signals in the resulting far-field pattern. One of such
methods models the measurement environment as a multiple source scenario
whereby the collected near-field data is attributed to the AUT and some
scattering centers in the vicinity of the AUT. In this way, the contributions
of the AUT at the probe can be separated from those of the disturbers during
the near-field far-field transformation if the disturber locations are known.
In this paper, we present ways of modeling the scattering centers on
equivalent surfaces such that echo suppression is possible with only partial
or no information about the geometry of the scatterers. |
