中文摘要本发明涉及一种基于自适应转移概率矩阵的交互多模型跟踪方法,包括以下步骤:首先计算状态估计的交互作用,然后通过卡尔曼滤波或粒子滤波,获得各模型的输出,进而更新模型概率,输出结果,根据模型概率的变化,自适应调节状态转移概率,用于下一时刻跟踪。本发明避免模型的转移概率是先验给定,根据模型概率的变化,自适应调节状态转移概率;本发明可以对目标进行稳定的跟踪,获取目标的准确轨迹,判断目标的运动趋势;本发明提升雷达的跟踪性能。

英文摘要The invention relates to an interactive multi-model tracking method based on a self-adaptive transition probability matrix. The interactive multi-model tracking method comprises the steps of calculating interaction effect of state estimation, acquiring output of each model through Kalman filtering or particle filtering, updating model probability, outputting results, and regulating state transition probability in a self-adaptive manner according to variation of the model probability for tracking at the next moment. The interactive multi-model tracking method avoids the problem that the transition probability of models is priori given, and regulates the state transition probability in a self-adaptive manner according to variation of the model probability; the interactive multi-model tracking method can track a target stably, acquires an accurate trajectory of the target, and judges the movement tendency of the target, and the interactive multi-model tracking method improves the tracking performance of a radar.
