The IsoFilter™ Technique: A Method of Isolating the Pattern of an Individual Radiator from Data Measured in a Contaminated Environment

This paper describes a novel method, termed the IsoFilter Technique, for isolating in measured data the radiation pattern of an individual radiator from among a composite set of radiators that form a complex radiation distribution. This technique proceeds via three successive steps. The first is a spherical NFFF transform on an over-sampled data set. This is followed by a change of coordinate system. This is followed in turn by filtering of the spherical modes in the domain to isolate a radiating source. The end result yields an approximate pattern of the individual radiator, largely uncontaminated by the other competing sources of radiation.
