Abstract:
1. A method for localizing one or more sources, each source (emitters) being in motion relative to a network of sensors, the method comprising the steps of: separating the sources in order to identify the direction vectors associated with the response of the sensors to a source at a given incidence, said incidence angles varying depending on the position of the sensors network relative to said sources; associating direction vectors a wherein the direction vectors a wherein the associating step comprises: Step ASE-1: Initialization of the process at k=2, Step ASE-2: For 1<m<M determining the indices i(m) in using the relationship the direction vector a k,m and the vectors b i identified at the instant t k+1 for (1<i<M), setting up a function β m (t k )=d(a km , a om ), wherein d(u, v)=1− Step ASE-3: For 1<m<M performing the operation a Step ASE-4: Incrementing k←k+1 and if k<K returning to the step ASE-1, Step ASE-5: Starting from the family of instants θ={t where M is the number of transmitters.
