The passive target motion analysis (TMA) of a source in constant turn motion by a platform moving with a constant velocity vector is addressed in this paper. The observer acquires either bearing measurements or bearing and frequency measurements. Firstly the bearings-only TMA is investigated. The observability conditions are established and the performance is analyzed with the Cramér-Rao lower bound. The behavior of the maximum likelihood estimator is evaluated using Monte-Carlo simulations, for various typical scenarios. The bearings and frequencies TMA is subsequently analyzed in the same way. Its performance is compared with that of the bearings-only TMA to evaluate the improvement
