发明名称 METHOD FOR LOCATING MULTIPLE RAYS OF A SOURCE WITH OR WITHOUT AOA BY MULTI-CHANNEL ESTIMATION OF THE TDOA AND FDOA
摘要 A method and system for locating an emitter E transmitting a signal toward a receiver A comprising N radio frequency channels (N≧1), the characteristics of said signal being unknown to the receiver and said signal being reflected off P reflectors Bi (P≧1) of known positions, includes a step of multi-channel joint estimation/detection of the time differences of arrival or TDOA τi and of the frequency differences of arrival or FDOA fi for each reflected path, a step of angular estimation of the direction &thetas;1 of the direct path of the signal emitted by a goniometry procedure, and a step of location in the plane of the position (x,y) of the emitter E on the basis, at least, of the pairs (τi, fi).
