Imm smoothing
Witryna15 lut 2024 · A suboptimal algorithm to fixed-interval and fixed-lag smoothing for Markovian switching systems is proposed, which infers a Gaussian mixture approximation of the smoothing pdf by combining the statistics produced by an IMM filter into an original backward recursive process. A suboptimal algorithm to fixed-interval … WitrynaThe fixed-interval IMM smoothing algorithms can be found in [13] and [14]. In this paper we propose a novel locally adaptive parallel es-timation scheme which can be …

And the process, i.e. the kinematics of the observed airborne object in this case, is typically best described by nonlinear models.
Witryna[68, 1]; and the interacting multiple model (IMM) algorithm [31, 28, 96]. A second-order extension of the IMM algorithm was developed in [26]. Some researchers have developed approaches to avoid the two-stage nature of manoeuvre de-tection and compensation implied by methods like variable dimension filtering. These include
In this important step, the latest track prediction is combined with the associated plot to provide a new, improved estimate of the target state as well as a revised estimate of the errors in this prediction. There is a wide variety of algorithms, of differing complexity and computational load, that can be used for this process.
