  • Method for locating a source by multi-channel estimation of the TDOA and FDOA of its multipath components with or without AOA
    Patent number: 8718674
    Abstract: 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 ?i and of the frequency differences of arrival or FDOA fi for each reflected path, a step of angular estimation of the direction ?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 (?i, fi).
