Thomas Kropfreiter, Jason L. Williams, Florian Meyer

摘要:

提出了一种基于泊松/多伯努利模型的可扩展检测前跟踪(TBD)跟踪方法。为了限制计算复杂度,我们近似的确切的多伯努利混合后验概率密度函数(pdf)的多伯努利pdf。基于和-积算法的数据关联和伯努利分量的回收使得能够在有限的计算资源下检测和跟踪低可观测对象。我们的仿真结果表明,一个显着改善的跟踪性能相比,一个国家的最先进的TBD方法。

英文摘要:

We propose a scalable track-before-detect (TBD) tracking method based on a Poisson/multi-Bernoulli model. To limit computational complexity, we approximate the exact multi-Bernoulli mixture posterior probability density function (pdf) by a multi-Bernoulli pdf. Data association based on the sum-product algorithm and recycling of Bernoulli components enable the detection and tracking of low-observable objects with limited computational resources. Our simulation results demonstrate a significantly improved tracking performance compared to a state-of-the-art TBD method.
