Analysis and modeling of uncertain system in complex environment

In complex battlefield environment all kinds of the uncertainties for target tracking make the analysis and modeling of tracking system irresolvable. Aiming at different levels of system uncertainty, the correspondent modeling methods are introduced. First, the stochastic process model is investigated which includes target process equation and sensor measurement equation. Second, joint state-class probabilistic density is given for realizing target tracking and classification simultaneously. Finally, the joint target detection, tracking and identification based on finite-set statistics theory is represented for multi-sensor multi-target tracking.
