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.
Claims22
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.
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.
