C. Jauffret et D. Pillon, OBSERVABILITY IN PASSIVE TARGET MOTION ANALYSIS, IEEE transactions on aerospace and electronic systems, 32(4), 1996, pp. 1290-1300
The nature of observability of nonlinear systems encountered in passiv
e target motion analysis (TMA) is carefully examined. The approach pro
posed here is based upon a well chosen criterion which allows us to an
swer the major observability questions.
