Furthermore, RADAR and automatic identification system (AIS) are two sensors commonly used onboard for tracking maritime targets. The fusion of these two sensors, utilizing complementary information and handling the conflicting data, gets increasingly important during autonomous sailing. However, due to the immaturity of multi-target tracking methods, the fusion was hardly systematically discussed, when there are missed detections from certain single sensors and conflicts between two sensors. As the new multi-target tracking methods have been proposed, this paper first presents a sequential measurement-level fusion approach of RADAR and AIS based on the newest random finite set (RFS)-based filter — Poisson multi-Bernoulli mixture (PMBM) filter. The comparison of the performance both using sequential fusion and using the sensor information individually is presented in this article. Then the proposed sequential fusion of RADAR and AIS based on PMBM filter was applied to a real maritime case. The tracking results are given and the performance is analyzed. Keyphrases: Heterogeneous Sensor Fusion, PMBM filter, Radar/AIS fusion, data association, multi-target tracking
