Patent ID: 7579828

Claim:
A method for locating a mobile magnetic target using magnetic measurements performed with mobile magnetic detection means, which includes: a)—a determination at a moment in time t 1 of a first position range of said mobile target with said mobile magnetic detection means, and a second position range of said mobile target at a later moment in time t 2 , with said mobile magnetic detection means, b) calculation of a target velocity component of said mobile magnetic target along a direction and of a theoretical position range of the target with respect to a trajectory of said mobile magnetic detection means, defined relative to said direction as a function of said velocity component, at a subsequent theoretical moment in time t 3 , c)—a determination of a third position range of said mobile magnetic target with said mobile magnetic detection means moving along said theoretical position range, and a determination of an approached position and of the trajectory of said mobile magnetic target, as a function of said first, second and third position ranges.
