Abstract

Det beskrives fremgangsmåter og anordninger for elektromagnetiske undersøkelser med kontrollert kilde. Mer bestemt transmitteres et tidsvarierende elektromagnetisk signal på et første sted, og et elektromagnetisk signal som respons på det transmitterte signalet mottas på et andre sted. Det mottatte signalet har en transientresponskomponent og en stasjonærtilstandkomponent. Det mottatte signalet blir kontinuerlig registrert i et forhåndsbestemt tidsintervall, og data som svarer til transientresponskomponenten og stasjonærtilstandkomponenten trekkes ut fra det mottatte signalet. Transientresponsdata og stasjonærtiltandresponsdata blir invertert sammen for identifisering av en undergrunnsegenskap, så som en resisti vitet.
