In both military and civilian fields, maneuvering target tracking technology plays an important part. With the rapid development of modern aeronautics and astronautics technology, flight vehicles get faster and faster, and their maneuverability gets higher and higher as well. The characteristics of complexity, randomness and multiplicity resulted from maneuver further make the tracking task very difficult both theoretically and practically. Although lots of research work has been established on maneuvering target tracking, generally speaking, research aiming at tracking of both high-speed & large-maneuver and low-speed & flexible-maneuver targets is still not enough for engineering requirement. First, we analyze the basic theory of maneuvering target tracking deeply, of which Bayesian filtering algorithms are mainly summarized, and existing filtering methods are classified in the framework of Bayesian theory. Second, typical maneuvering target tracking problems are classified into two kinds: high-speed & large-maneuver target tracking and low-speed & smart-maneuver target tracking, and modified input estimation algorithm based on fading factor and an improved adaptive turn rate calculating method are proposed respectively according to their motion characteristics. Third, new algorithms are simulated respectively by simulation instances, and simulation results verify the validity of the new algorithms. The main fruit of the dissertation is as follows: (1)Analysis on Bayesian filtering algorithm We start from the Bayesian theory, and make an exhaustive analysis on its principle. Existing filtering algorithms are classified to optimal filtering algorithms and suboptimal filtering algorithms. And then we make a deep study and find out the merits and drawbacks of the existing algorithms. (2) We introduce a fading factor into the existing input estimation algorithm and propose a new algorithm called modified input estimation algorithm based on fading factor. The strengths of the new algorithm compared with the existing ones are as follows: without maneuver detection, able to resolve problems like tracking performance degrade resulted from state mutation. Then we apply the new method to the tracking of high-speed & large-maneuver targets. Simulation results show that the new method has a better tacking performance than the existing methods. (3) We optimize the adaptive turn rate calculating method based on existing methods. The strengths o...
