Probe correction in Spherical Near Field (SNF) measurements is typically performed during the NF/FF transformation assuming a probe with limited |μ|=1 spectrum [1]–[2]. This requirement leads to challenging probe designs, especially if the required bandwidth is wide. For this reason, in many practical cases, higher order spherical modes could be radiated. In this paper, the source of higher order...
Classical probe corrected Spherical Near Field (SNF) measurement assumes probes with limited |µ|=1 spectrum [1]–[3]. This requirements is needed to fully compensate the effect of the probe during the NF/FF transformation [3]. If the probe spectrum contains higher order modes, a residual error will affect the measured pattern (probe modal truncation). This requirement leads to challenging probe designs,...
In this paper data coming from a GNSS satellite measurement campaign will be used to perform an advanced analysis regarding the interaction between antennas, satellite structure and appendages.
This paper reports the findings of a comparative investigation of two versatile echo suppression techniques applicable to general antenna near field measurement scenarios with echoes of unknown origin. Both techniques are based on spatial filtering of the measured field taking advantage of the apriori knowledge of the antenna size and can be applied to near field measurements in any canonical scan...
