摘要
在避碰过程中,舰船一般处于机动状态。因而,对机动目标运动要素解算的精度直接影响到避碰的效果。通过对多种模型的比较,选用了“当前”统计模型,“当前”统计模型相对于其他模型能够更为真实地反映目标的机动变化。仿真结果表明,此算法收敛迅速并有较高精度,其解算所得的目标运动要素能够满足舰船避碰等实用要求。
A ship is generally maneuvering in the process of collision avoidance. Therefore, the precision of calculation result for maneuvering target motion element will have direct influence on effect of ship collision avoidance. After comparing many prevalent target models and tracking algorithms, this paper selects the ＂current＂ statistic model, which can be more actual to reflect the element maneuvering change than other models. The simulation results indicate that the algorithm converges quickly and accurately, and the calculation result can meet with the requirement of ship collision avoidance.
