摘要:

输出是监视区域中存在的各目标贡献之和的函数的传感器被称为叠加传感器。在这篇通信中,提出了用于叠加传感器的基于目标聚类的多伯努利滤波器。各目标根据它们所照射的分辨单元集合进行聚类。严格推导了单目标后验密度,并将所有目标的密度组合成近似的多目标后验,这使得多伯努利密度相对于叠加传感器的似然而言是共轭的。还给出了所提算法的高斯实现,其中更新方程的多维性和非线性由 sigma 点变换处理。仿真结果表明,在面对多目标相互作用以及两个目标长期重叠时,所提算法是有效的。

英文摘要:

The sensor whose output is a function of the sum of contributions from targets present in the surveillance area is called superpositional sensor. In this letter, target clustering based multi-Bernoulli filter for superpositional sensors is proposed.Targets are clustered according to the set of resolution cells illuminated by them. Single target posterior density is strictly derived, and densities of all the targets are combined to a approximate multi-target posterior, which makes the multiBernoulli density is conjugate with respect to the likelihood of superpositional sensors. The Gaussian implementation of the proposed algorithm is also presented, where the multidimensionality and the nonlinearity of update equation are handled by sigma point transformation. The simulation results illustrate that the proposed algorithm is effective confronted with the interaction of multiple targets and long term overlapping of two targets.
