Abstract

"SISTEMA DE INFORMAçãO DE IMAGEM DE ESTRUTURAS EM REGIõES ILUMINADAS POR TRANSMISSOR RF, E MéTODO DE GERAçãO DE IMAGEM". Um sistema de imagem usando "luz do dia RF" criado por uma fonte de iluminação RF, tal como uma torre de transmissão de televisão, para gerar passivamente coeficientes de dispersão RF para múltiplos pontos dentro de um volume tridimensional prescrito iluminado por transmissor RF. Os coeficientes de dispersão provêem um padrão de interferência complexo tendo componentes de amplitude e fase que contêm todas informações necessárias para recriar uma imagem monocromática tridimensional do cenário iluminado. Uma correlação complexa coerente provê conteúdo de informação de cenário que é função somente da dispersão de cenário e geometria de coletor.
