The far field errors due to near field random noise are statistically bounded when performing cylindrical near to far field transform. In this communication, the far field noise variance it is expressed as a function of the measurement parameters and the near field noise variance. NIRQDUCflION So far [1] [2], expressions have been derived to predict the effect of random errors in planar near field antenna measurements. Similar equations are not available for cylindrical near field measurements.

Moreover, the far field S/N ratio, although being a quite appealing parameter, hides in its simplicity some important aspects.
