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 identification of a reference transmitter E0 through an estimation of its direction of arrival AOA-TDOA pair (θref,Δτref) on the basis of the knowledge of the position E0 of the reference transmitter and of those of the stations at A and B, an estimation of the direction of arrival of the transmitter or transmitters and of the reflectors (or estimation of the AOA) on the first station A, the correction of the errors of asynchronism between the station A and the station B by using the reference transmitter E0 and the location of the various transmitters on the basis of each pair (AOAi, TDOAi).
