Abstract

A method and device are disclosed for recognizing a target (T) among a plurality of n known targets Ti (with i=1, 2, 3, . . . , n). According to the invention, by direct examination of said target (T) to be recognized and from first values (Cki) representative of a plurality of p recognition criteria Ck (with k=1, 2, 3, . . . , p), at least p third values (pCk(Ti)) are established representative of the probabilities that, for each recognition criterion (Ck), the target (T) to be recognized is each of said known targets (Ti); and said third values associated with the same known target (Ti) are merged while taking into account second values (PCk(Ti)) representative of the probabilities that a target (Ti) is recognized, in so far as criterion Ck is concerned, when it is examined so as to obtain n fourth values (p(Ti)), each of which is representative of the probability that the target to be recognized is one of the known targets (Ti).
