摘要:

高分辨率雷达传感器对于自动驾驶系统至关重要,但传统跟踪算法因每个目标生成多个测量值以及多径效应的存在而面临重大挑战。现有解决方案通常依赖于点目标假设或将多径测量视为杂波,而当前的扩展目标跟踪器在复杂多径环境中往往缺乏维持轨迹连续性的能力。为了解决这些局限性,本文提出了多径扩展目标通用标记多伯努利(MPET-GLMB)滤波器。基于标记随机有限集理论推导出一个统一的贝叶斯框架,用于联合建模目标存在、测量分割以及测量、目标和传播路径之间的关联。这种 formulations 允许在不需启发式后处理的情况下同时估计目标和反射体的轨迹。为了提高计算效率,开发了一种基于吉布斯采样的联合预测和更新实现。此外,引入了一种测量驱动的自适应出生模型,以在不事先知道目标位置的情况下初始化轨迹。实验结果表明,所提出的滤波器在模拟场景和真实世界汽车雷达数据中优于现有方法,实现了在动态多径环境中更精确的状态估计和更稳健的轨迹维护。

英文摘要:

High-resolution radar sensors are critical for autonomous systems but pose significant challenges to traditional tracking algorithms due to the generation of multiple measurements per object and the presence of multipath effects. Existing solutions often rely on the point target assumption or treat multipath measurements as clutter, whereas current extended target trackers often lack the capability to maintain trajectory continuity in complex multipath environments. To address these limitations, this paper proposes the multipath extended target generalized labeled multi-Bernoulli (MPET-GLMB) filter. A unified Bayesian framework based on labeled random finite set theory is derived to jointly model target existence, measurement partitioning, and the association between measurements, targets, and propagation paths. This formulation enables simultaneous trajectory estimation for both targets and reflectors without requiring heuristic post-processing. To enhance computational efficiency, a joint prediction and update implementation based on Gibbs sampling is developed. Furthermore, a measurement-driven adaptive birth model is introduced to initialize tracks without prior knowledge of target positions. Experimental results from simulated scenarios and real-world automotive radar data demonstrate that the proposed filter outperforms state-of-the-art methods, achieving superior state estimation accuracy and robust trajectory maintenance in dynamic multipath environments.
