摘　　要：针对高斯混合势平衡多目标多伯努利(GM-CBMeMBer)滤波器局限于固定出生位置且不能提供航迹信息的缺陷,为有效利用机载多普勒雷达的多普勒信息,提出了自适应单点航迹起始的带标签GM-CBMeMBer滤波器。在预测步骤,该滤波器通过引入航迹标签提供航迹信息,并选取可能对应新生目标的量测,根据转换的位置量测和多普勒量测分别得到新生目标初始状态的位置分量和速度分量;在更新步骤,依次使用转换的位置量测和多普勒量测序贯更新目标状态。仿真结果表明,所提算法航迹起始性能良好,并且能够有效提供航迹信息。Aiming at the problem that the Gaussian Mixture Cardinality Balanced Muhi-Target Multi- Bernoulli （GM-CBMeMBer） filters are limited to the fixed birth position and cannot provide track information, a labeled GM-CBMeMBer filter with adaptive one-step track initiation is proposed, which makes full use of the Doppler information of the airborne Doppler radar. In the predicting step, the proposed algorithm provides track information by introducing track label. After selecting the measurements that may correspond to the newborn targets, the position estimation and velocity estimation of newborn targets are calculated by using the converted position measurements and Doppler measurements respectively. In the updating step, the target states are updated sequentially by using Doppler measurements after they are updated with position measurements. The results of simulation show that the proposed algorithm performs well in track initiation and can effectively provide track information.
