METHOD OF MULTI-TRANSMITTER AND MULTI-PATH AOA-TDOA LOCATION COMPRISING A SUB-METHOD FOR SYNCHRONIZING AND EQUALIZING THE RECEIVING STATIONS

摘要

Method and system for locating one or more transmitters Ei in the potential presence of obstacles Rp in a network comprising at least one first receiving station A and one second receiving station B asynchronous with A, characterized in that it comprises the identifying of a reference transmitter E0 by estimating its AOA-TDOA pair direction of arrival (ϑref,ΔTref) from the knowledge of the position EO of the reference transmitter and of those of the stations of A and B, estimating the direction of arrival of the transmitter or transmitters and reflectors (or estimating the AOA) on the first station A, the correcting of the asynchronism errors between station A and station B using the reference transmitter E0 and the location of the various transmitters on the basis of each pair (AOAi, TDOAi).
