0.2.3.3.3.1.2 Allocation Parameters
The reflection points reported in the point cloud are associated with existing tracking instances. Points that are not associated are subjects for the allocation decision. Each candidate point is clustered into an allocation set. To join the set, each point must be within maxDistance and maxVelThre from the set’s centroid. When the set is formed, it must have more than setPointsThre members, and pass the minimal velocity and SNR thresholds. Table 7 lists these parameters.
