1. Zastrzezenie patentowe Sposób wyznaczania odleglosci zródla pola elektromagnetycznego w postaci anteny magne¬ tycznej stanowiacej elementarny dipol magnetyczny o dowolnej i nieznanej orientacji w osrod¬ ku elektrycznie stratnym, niejednorodnym i anizotropowym, przez pomiar w punkcie odbioru, znajdujacym sie w strefie bliskiej, najwiekszej amplitudy magnetycznej skladowej pola i wy¬ znaczaniu odleglosci zródla tego pola, z zaleznosci sredniej wartosci rzeczywistej amplitudy wypadkowego wektora magnetycznej skladowej pola wzbudzonego przez taki elementarny dipol od odleglosci tego dipola do punktu odbioru, znamienny tym, ze w pierwszym etapie wyznacza sie przyblizone odleglosci zródla pola z co najmniej dwóch punktów pomiarowych w strefie bliskiej i okresla przyblizony kierunek zródla pola, a w drugim etapie ponownie mierzy sie w Jednym z tych punktów pomiarowych najwieksza amplitude magnetycznej skladowej pola, przy czym odleglosó zródla pola wyznacza sie albo z zaleznosci najkorzystniej zwiek¬ szonej o 2 dB, Jesli os odbiorczej anteny magnetycznej Jest zgodna z przyblizonym kierunkiem do zródla pola, albo z zaleznosci najkorzystniej zmniejszonej o 2 dB, Jesli os odbiorczej anteny magnetycznej Jest prostopadla do przyblizonego kierunku do zródla pola, sredniej wartosci rzeczywistej amplitudy wypadkowego wektora magnetycznej skladowej pola. *-2dB~* //. /134 445 N / y / / / / o, /*.
