Deep probabilistic model-based aircraft trajectory prediction for general airports
通用机场的航空器轨迹预测是保障低空飞行安全和提高运行效率的关键技术,通用航空飞行具有任务多样、路径灵活、环境敏感等特点,传统的预测方法难以准确建模这些复杂特性.为此,提出了一种基于深度概率模型的轨迹预测框架,采用条件变分推断方法来建模轨迹的概率分布.通过引入隐变量来捕捉影响飞行轨迹的潜在因素,并通过集成物理约束和轨迹平滑正则化,确保生成的轨迹符合飞机动力学特性和飞行规则.实验结果表明,所提方法在位移误差指标上相比最先进的基准方法分别降低了 18.3%和 16.7%.消融实验验证了各个模块的有效性,其中变分推断贡献最大(15.2%的性能提升),环境感知模块作用显著(8.7%的性能提升),为通用机场的安全运行提供了有力支撑.
Aircraft trajectory prediction is a key technology for airports to ensure low-altitude flight safety and improve operational efficiency.General aviation flights are characterized by diverse tasks,flexible paths,and environmental sensitivity.Traditional prediction methods struggle to accurately model these complex characteristics.This paper proposes a trajectory prediction framework based on deep probability models,and employs conditional variational inference methods to model the probability distribution of trajectories.By introducing latent variables to capture the potential factors influencing flight trajectories and integrating physical constraints and trajectory smoothing regularization,the framework ensures the generated trajectories conform to the aircraft's dynamic characteristics and flight rules.Experimental results show the proposed method reduces the displacement error index by 18.3%and 16.7%respectively compared other advanced benchmark methods.The ablation experiments validate the effectiveness of the modules.Among them,variational inference contributes the most(improving performance by 15.2%)and the environmental perception module also plays a critical role(improving performance by 8.7%),ensuring the safe operation of airports.
