Abstract

En metode og apparat for konstruksjon av signal for kartlegging ved bruk av en elektromagnetisk kontrollert kilde er her beskrevet. I én utførelsesform, er det beskrevet en metode som inkluderer bestemmelsen av en første bølgeform og en annen bølgeform, den første bølgeformen og den andre bølgeformen relaterer seg til et kombinert frekvensspekter og båndbredde assosiert med en geofysisk kartleggingslinje. Så et signal er konstruert ved sekvensering av den første bølgeformen og den andre bølgeformen. Dette signalet kan bli brukt i en sender, som kan bli trukket av et fartøy langs en geofysisk kartleggingslinje.
