Abstract

En 中文

• This paper develops a refined multipath model that incorporates modulation effects from reflective surface, better matching complex real-world terrains than classical point-based approaches. • Combined with a sparse Bayesian off-grid framework and hyperparameter optimization, the method reduces model mismatch and off-grid error, enhancing low-elevation target height estimation. • Simulations and measured data validate the method’s superiority, especially in complex coastal areas, demonstrating its effectiveness and refined model’s performance.
