There are all those algorithms for target tracking

1.Modeling of maneuvering target in Cartesian Coordinate System-Based on the in-depth study of time-dependent model, an adaptive constant acceleration model--ACA model is proposed, and its equivalence with non-zero mean time-dependent model is confirmed in both theory and simulation, and under the same conditions, the complexity and computation of ACA model are greatly reduced and can be more effectively applied in engineering practice. is greatly reduced and can be applied to engineering practice more effectively.

2. Modeling of maneuvering target in polar coordinate system - A general coordinate system transformation method of filtering model is given and used to establish the target motion model in polar coordinate system, which can realize the decoupling of the state equations under certain conditions and the decoupling condition is very easy to be satisfied, which will greatly reduce the computation amount. Compared with the non-decoupled classical algorithm, the biasedness of the radial distance estimation is eliminated with comparable accuracy of the direction angle estimation, thus greatly improving the accuracy of the radial distance estimation, and thus it has a good prospect of engineering application.

3. Multi-model algorithm and data association-Through the research on interactive multi-model (IMM) algorithm and probabilistic data association/joint probabilistic data association (PDA/JPDA) algorithm, for the structural and theoretical deficiencies of IMMPDA algorithm proposed by Bar-Shalom and Blom et al. and in accordance with the idea of global optimization, a new integrated IMMPDA/IMMJPDA algorithm--C-IMMPDA/C-IMMJPDA algorithm, which makes the IMMPDA algorithm perfect in structure and theory, and the simulation results show that the C-IMMPDA/C-IMMJPDA algorithm reduces the computation amount while the overall performance is significantly improved.

4. Tracking Start-The study of the two-point extrapolation filter start method leads to the derivation of a new method for constructing a wavegate in a finer way. The method can utilize a priori information about the target velocity limit. Simulations show that the wavegate constructed by this method is more reasonable compared to other wavegate construction methods.

5. Fusion of dissimilar information-Through the research on the application of electronic map in the ground tracking system, a target tracking correction method based on the electronic map is given, so that the target can be distinguished more clearly, and the results of the field test confirm the feasibility of this method, which makes the output of the tracking-while-scanning (TWS) system can be better applied to the battlefield reconnaissance.

6. Tracking system design and software implementation - the overall implementation of the mobile multi-target tracking system is studied, combined with the helicopter long-range battlefield reconnaissance radar TWS system project research, from the system analysis, modeling to the implementation, simulation, a relatively complete set of tracking system design scheme is proposed. And on the basis of the previous research, designed a set of maneuvering multi-target tracking simulation software system, by using object-oriented programming ideas, according to hierarchical structure, so that its level is clear, simple to use, with strong versatility and easy to maintain, for further research work to provide an effective simulation environment.
