摘要： A system and a method for displaying an emitter location are disclosed. The system includes a plurality of receivers at different locations in a field. Each receiver generates a receiver signal that depends on the magnitude of a signal from the emitter. The system also includes a processor that receives the receiver signal and generates a likelihood map indicative of an approximation of a probability as a function of position in the field of the emitter location. The likelihood map includes a plurality of receiver maps. Each receiver map includes a probability as a function of position in the field of the emitter location based on the signal magnitude for at least one of the receiver signals. Each receiver map may depend on a ratio of the signal magnitudes from a corresponding pair of the receivers, or on one of the signal magnitudes from a corresponding one of the receivers.

摘要： 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.
