After TBM type confirmation, what filtering is used to determine if the threat meets proper kinematics?

• A. Contender's List
• B. Outside Lethality Zone
• C. Location Uncertainty
• D. Azimuth Uncertainty

Answer: (A)

When the system has confirmed the threat type as a TBM, it uses a filter that builds a Contender’s List. This step sifts through all detected tracks and keeps only those that exhibit the expected TBM motion—ballistic trajectory, speed and altitude consistent with a TBM profile, and timing that matches a launch-to-impact scenario. Tracks that don’t line up with TBM kinematics are removed from consideration, so only credible TBM-like threats advance toward engagement decisions. Other filters address different concerns—whether the predicted impact point lies within the lethal envelope, or how uncertain a track’s location or bearing is—but they don’t discriminate based on the kinematic fit as directly as the Contender’s List does.
