Analysis of localization methods for unintended emitting sources

OpenAlex İngilizce

Abstract This paper presents an analysis of localization and tracking of unintended emissions from electronic devices using computer simulations. The available localization and tracking methods assume that the device is in the far-field region of the array. However, the received power of unintended emissions is very low and, therefore, requires near-field techniques. In the near-field, the performance of far-field schemes degrades since they ignore the effect of range on phase characteristics. Computer simulation results for localization and tracking methods developed by the authors are summarized to analyze the effects of near and far-field regions.
