System for identifying a signal source
First Claim
1. A system for identifying a signal source in a predetermined space, comprising:
- a plurality of sensing units arranged at different locations of the predetermined space to detect signals in the predetermined space;
at least one recording unit connected to the sensing units and arranged to separately and simultaneously record a detected signal at each of the sensing units that detects the signal; and
a processing unit configured to receive signal recordings from the at least one recording unit;
the processing unit comprising;
a first storage area configured to store a set of identified signatures corresponding to a plurality of signal sources in the predetermined space;
a second storage area configured to store parameters related to the conditions under which the recordings of the signal are made; and
an identifying unit, wherein;
the identifying unit is configured to;
determine a spectrum of the recorded signal;
detect a line emerging from background noise of the spectrum by using a predetermined emergence threshold;
compare the line with some or all of the signatures included in the set of identified signatures;
select at least one signature corresponding to the line to create at least one signature/line pair; and
identify a source of the signal based on the created at least one signature/line pair.

Abstract
A system for identifying a signal source in a predetermined space, the system including multiple sensing units arranged at different locations to detect signals in the predetermined space. The system also includes one or more recording units arranged to separately and simultaneously record a detected signal at each of the sensing units that detects the signal. The system further includes a processing unit including a first storage area configured to store a set of identified signatures corresponding to multiple signal sources in the predetermined space, and a second storage area configured to store parameters related to the conditions under which the recordings of the signal are made. The processing unit also includes an identifying unit that is programmed to identify a signal source by comparing a determined signal spectrum with some or all of the signatures included in the set of identified signatures.
