1. A method for analyzing signals transmitted from a transmitter, the method comprising the steps of:

  • obtaining a noise measurement at a remote location when no signal is transmitted from the transmitter;

    transmitting an electromagnetic signal from the transmitter;

    detecting the electromagnetic signal at the remote location by measuring a detected electromagnetic field transmitted by the transmitter, the detected signal having a noise free component;

    estimating the noise free component of the detected signal using the noise measurement and a magnitude of the detected signal; and

    locating the transmitter using the noise free component.
