| 摘要: |
| 在机载多普勒雷达多目标跟踪(MTT)过程中，多普勒盲区(DBZ)的存在易造成连续漏检，严重地影响目标跟踪性能。针对这一问题，提出了DBZ下基于高斯混合势平衡多目标多伯努利(GM-CBMeMBer)的多目标跟踪算法。首先将带最小可检测速度(MDV)的检测概率模型代入CBMeMBer更新公式中，然后推导了带MDV和多普勒信息的GM-CBMeMBer更新公式。仿真结果表明，相比未并入多普勒和MDV信息的GM-CBMeMBer，所提算法能有效改善DBZ条件下的多目标跟踪性能。 |

| Abstract: |
| In multi-target tracking (MTT) for the airborne Doppler radar, the existence of Doppler blind zone (DBZ) results in a series of missed detections, which strongly deteriorates tracking performance. To overcome this problem, a MTT algorithm based on Gaussian mixture cardinality balanced multi-target multi-Bernoulli (GM-CBMeMBer) is proposed in the presence of DBZ. First, we incorporate the detection probability model with minimum detectable velocity (MDV) into CBMeMBer, and then derive the update formulas of a novel GM-CBMeMBer where the MDV and Doppler information are fully exploited. The results of simulation show that the proposed algorithm outperforms the GM-CBMeMBer which doesn’t incorporate the Doppler and MDV information in the presence of DBZ. |
