Aircraft Tracking and 4D Trajectory Prediction

Our group develops a set of aircraft tracking and four-dimensional trajectory prediction algorithms based on the Stochastic Hybrid System (SHS) modeling and hybrid state estimation algorithms.

Stochastic Linear Hybrid System (SLHS) model / Residual-Mean Interacting Multiple Model (RMIMM) algorithm [1]
SLHS model / RMIMM for multiple-target tracking [2]
SLHS model / RMIMM with intent inference: Intent-based Trajectory Prediction
SLHS model / probabilistic reachability analysis: Probabilistic Trajectory Prediction and Conflict Detection
SLHS with state-dependent-transition / State-Dependent-Transition Hybrid Estimation (SDTHE) algorithm [3], [4]
Nonlinear SHS with state-dependent-transition / SDTHE-based algorithm: Estimated Time of Arrival (ETA) Prediction in Terminal Airspace

Arrival aircraft trajectories in the horizontal plane [4]

Aircraft trajectories for a descent phase [3,4]

Trajectories of multiple aircraft with clutter [2]

Trajectory of an aircraft along a Continuous Descent Approach (CDA) procedure [ETA prediction]
