Method for identifying a signal source
First Claim
1. A method for identifying a signal source in a predetermined space, comprising:
- inventorying a set of identified signatures corresponding to a plurality of signal sources;
recording a signal simultaneously at different locations of the predetermined space;
storing parameters related to the conditions under which the recordings are made;
determining a spectrum of the signal;
detecting a line emerging from background noise of the spectrum by using a predetermined emergence threshold;
comparing the line with some or all of the signatures included in the set of identified signatures;
selecting at least one signature corresponding to the line to create at least one signature/line pair; and
identifying a source of the signal based on the selecting step.

Abstract
A method for identifying a signal source in a predetermined space, the method including inventorying a set of identified signatures corresponding to a plurality of signal sources and recording a signal simultaneously at different locations of the predetermined space. Parameters related to the conditions under which the recordings are made are then stored, and a spectrum of the signal is determined. The method also includes detecting a line emerging from background noise of the spectrum by using a predetermined emergence threshold. The line is then compared with some or all of the signatures included in the set of identified signatures, and at least one signature corresponding to the line is selected to create at least one signature/line pair. Finally, a source of the signal is identified based on the selecting step.

14. A method for identifying a signal source in a vehicle, comprising:
-
providing a set of identified signatures, wherein each signature is associated with a signal source;
providing a plurality of sensors at different locations of the vehicle;
creating at least one original recording of a signal detected by at least one of the sensors;
storing parameters related to the conditions under which the at least one recording is created, wherein one of the parameters is related to speed of the vehicle;
determining a spectrum of the signal;
detecting at least one line emerging from background noise of the spectrum by using a predetermined emergence threshold;
comparing the at least one line with at least one of the signatures in the set of identified signatures;
corresponding at least one of the signatures to the at least one line; and
identifying a source of the signal based on the corresponding step. - View Dependent Claims (15, 16, 17, 18)
