Abstract

A system and method determines the location of a transmitter. At least one receiver receives a signal from the transmitter and at least one proxy receiver is an object that reflects and/or refracts a signal along an arriving path to the at least one receiver. A processor is operative with the at least one receiver and determines the location of the at least one proxy receiver based on one of querying a look-up table or extracting image features from the mapping system and determining the location of the transmitter based on the time of arrival and at least one of angle of arrival of signals from the at least one proxy receiver and transmitter.
