一種幅度信息輔助多伯努利濾波算法
[Abstract]:In many multi-target tracking scenarios, the return amplitude of target is usually stronger than that of false alarm clutter. The accuracy of multi-target estimation can be improved by establishing a more accurate likelihood function of target and false alarm clutter. In this paper, an amplitude information aided multiple Bernoulli filter (Amplitude Information Assistant Multi-Bernoulli Filter,AIA-MBer F) algorithm based on random finite sets is proposed. In this algorithm, amplitude information is introduced into the updating process of multiple Bernoulli filtering by establishing amplitude likelihood function, and the implementation methods of Gao Si mixture (Gaussian Mixture,GM) and sequential Monte Carlo (Sequential Monte Carlo,SMC (SMC) for linear and nonlinear models are presented. Simulation results show that the proposed algorithm can obtain more accurate and stable target number and corresponding target state estimation than the traditional multi-Bernoulli filter (Multi-Bernoulli Filter,MBer F), regardless of the GM or SMC implementation.
