Abstract :
Classical bearings-only target motion analysis (TMA) are restricted to constant motion parameters (usually: position and velocity). However most of the interesting sources have maneuvering abilities, degrading, thus, dramatically the TMA performance. A basic idea consists of modelling the states of the source by a hidden Markov model (HMM). The main point is then to optimize the observer trajectory using methods derived from the general theory of dynamic programming
