SYSTEM AND METHOD FOR DETERMINING THE LOCATION OF A TRANSMITTER USING PASSIVE REFLECTORS OR REFRACTORS AS PROXY RECEIVERS AND USING DATABASE QUERYING

摘要

A system and method determines the location of a transmitter. At least onereceiver receives a signal from the trasmitter(64) and at least one proxyreceiver is an object that reflects and /or refracts a signal along anarriving path to the at least one receiver. A processor(66) is operative withthe at least one receiver and determines the location of the at least oneproxy receiver based on one of querying a look-up table or extracting imagefeatures from the mapping system and determining the location of thetrasmitter based on the time of arrival and at least one of angle of arrivalof signals from the at least one proxy receiver and transmitter.
