ABSTRACT:
A method for localizing one or more sources, the source or sources being in motion relative to a network of sensors, comprises a step for the separation of the sources in order to identify the direction vectors associated with the response of the sensors to a source at a given incidence. The method comprises the following steps of associating the direction vectors a1p(1)m. . . aKp(K)mobtained for the mthtransmitter and, respectively, for the instants t1. . . tKand for the wavelengths λp(1). . . , λp(k), and localizing the mthtransmitter from the components of the vectors a1p(1)m. . . aKp(K)mmeasured with different wavelengths.
