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.

Table 7. Allocation Parameters

PARAMETER DEFAULT DIM DESCRIPTION
SNR threshold 0 Minimum total SNR for the allocation set, linear sum of power ratios
SNR Obscured threshold 800 - Minimum total SNR if the allocation set is behind another track with respect to the radar module.
Velocity threshold 0.1 m/s Minimum radial velocity of the allocation set centroid
Points threshold 15 Minimum number of points in the allocation set
maxDistanceThre 1 m2 Maximum squared distance between candidate and centroid to be part of the allocation set
maxVelThre 2 m/s Maximum velocity difference between candidate and centroid to be part of the allocation set
