Abstract:

In this paper, we focus on the problem of parameter identification in a class of linear system, where system parameter (SP) is nonlinearly coupled in dynamic transition matrix (DTM), such as the well-known maneuvering target tracking with unknown turn rate. By regarding these elements nonlinearly parameterized by SP in DTM as a group of new multiplicative parameters (MP) linearly coupled with system state, the original SP identification problem is equivalently transferred into that of MP. By doing this, MP exhibits linearity characteristic so that we propose a new EM algorithm to analytically identify MP with both accuracy and efficiency, instead of SP. Finally, the efficacy of the proposed method is illustrated in an example of estimating the turn rate in maneuvering target tracking.
