A new interacting multiple model particle filter based ballistic missile tracking method

摘要

This paper proposes a new method for trackingudthe whole trajectory of a ballistic missile from launch toudimpact on the ground. Multiple state models are applied forudthe ballistic missile movement descriptions during differentudphases, while the transition probabilities are modelled in audstate-dependent way. A radar sensor is applied to obtainudthe missile range, azimuth angle and elevation angle measurements.udBased on the state models and measurements,udan interacting multiple model based particle filter methodudis applied for tracking. Simulation studies show that theudproposed method outperforms the widely-applied extendedudKalman filtering based interacting multiple model for trackingudthe ballistic missile.
