Method and system for locating signal emitters using iterative residual weighting

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; determine estimated location data for the first device for each sensor or unique sensor pair; determine an estimated location of the first device using the estimated location data for each sensor or unique sensor pair; determine residual values for the estimated location data for each sensor or sensor pair; convert the residual values into corresponding weights for the estimated location data for each sensor or sensor pair; weight the estimated location data for each sensor or sensor pair by its corresponding weight; and update the estimated location of the first device using the weighted estimated location data for each sensor or sensor pair.
