METHOD FOR LOCALIZATION BY MULTI-CHANNEL ESTIMATION OF TDOA AND FDOA OF MULTI-PATH OF A SOURCE WITH OR WITHOUT AOA

摘要

Method and system for locating an emitter E transmitting a signal to a receiver A having N channels (N≥1), the characteristics of said signal being unknown to the receiver and said signal being reflected on P reflectors B (P≥1) of known positions characterized in that it comprises at least the following steps: Step 1: a step of estimation / joint detection multi-channel arrival time differences or TDOA τi and arrival frequency differences or FDOA f of each reflected path, Step 2: a step of angular estimation of the direction θ of the direct path of the signal emitted by a direction finding method, Step 3: a step of localization in the plane of the position (x, y ) of the emitter E from at least pairs (τ, f).
