Abstract

The passive target motion analysis (TMA) of a source in constant turn (CT) motion by a platform moving with a constant velocity (CV) vector is addressed. The observer acquires either bearing measurements or bearing and frequency measurements. Firstly the bearings-only (BO)-TMA is investigated. The observability conditions are established, and the performance is analyzed with the Cramer-Rao lower bound (CRLB). The behavior of the maximum likelihood estimator (MLE) 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 BO-TMA to evaluate the improvement brought about by frequency measurements in some typical scenarios. Tactical aspects are also investigated.
