1. A method of determining a location of a first device that emits a signal, comprising:
- providing at least three sensors separated and spaced apart from each other;
at each of the sensors, receiving the signal emitted by the first device;
acquiring the received signals for each of the sensors;
determining magnitudes of cross-correlations between the received signals for pairs of the sensors; and
determining the location of the first device from the magnitudes of the cross-correlations of the received signals.

Abstract
A method and system for determining a location of a first device that emits a signal: provide at least three sensors separated and spaced apart from each other; at each of the sensors, receive the signal emitted by the first device; determine the received signals for each of the sensors; determine cross-correlations of the received signals for pairs of the sensors; and determine the location of the first device from the magnitudes of the cross-correlations of the received signals.

11. A system for determining a location of a first device that emits a signal, the system comprising:
-
at least three sensors separated and spaced apart from each other, each of the sensors including a receiver adapted to receive the signal emitted by the first device and to acquire the received signals for each of the sensors; a network connecting the sensors and adapted to communicate data from the sensors; means for determining magnitudes of the cross-correlations of the received signals for pairs of the sensors; and means for determining the location of the first device from the magnitudes of the cross-correlations of the received signals. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
