Abstract
In locating a transmitter, a central processor calculates a matched filter detector output for each of one or more candidate transmitter locations by applying a linear filter to low frequency magnetic field measurements obtained at a plurality of receiver locations. The central processor then determines the location of the transmitter based on the one or more calculated matched filter detector outputs. The linear filter is derived for the one or more candidate transmitter locations
Claims50
A method for locating a transmitter, the method comprising:
- calculating a matched filter detector output for each of one or more candidate transmitter locations by applying a linear filter to low frequency magnetic field measurements obtained at a plurality of receiver locations, the linear filter being derived for the one or more candidate transmitter locations;
- and
- determining the location of the transmitter based on the one or more calculated matched filter detector outputs.
A method for locating a transmitter, the method comprising:
- maximizing a localization statistic by applying a linear filter to low frequency magnetic field measurements obtained at a plurality of receiver locations, the linear filter being determined based on a propagation model associated with one or more candidate transmitter locations;
- and
- locating the transmitter based on the maximized localization statistic.
An apparatus for locating a transmitter, the apparatus comprising:
- a central processor configured to calculate a matched filter detector output for each of one or more candidate transmitter locations by applying a linear filter to low frequency magnetic field measurements obtained at a plurality of receiver locations, the linear filter being derived for the one or more candidate transmitter locations, the central processor being further configured to determine the location of the transmitter based on the one or more calculated matched filter detector outputs.
