Stray signal source location in far-field antenna/RCS ranges

摘要

Various methods for mapping stray signal sources in far-field antenna/RCS test ranges are summarized. These methods use the quiet-zone field probe data at a single frequency or over a frequency band. Relative merits and drawbacks of the various methods are discussed. It is shown that relatively simple processing of the field-probe data can be used for complete mapping of the stray signal sources.
