Abstract
The acoustic surveillance by a passive sonar is the topic of that paper. We propose an automatic detection and tracking procedure of several frequency lines present in a frequency-time representation (called lofargram). Each frequency line being modeled as a first order Markov chain, we adapt a classic algorithm (Forward-Backward) in the literature of the Hidden Markov Models (HMM) to satisfy that need
