When two targets are converging, the priority is to handle the one that poses the immediate collision threat, using the best available track data to base your decisions. Focus on the higher-risk target because its potential to collide is greater and accurate prediction depends on a reliable track. Keep the other target in view by maintaining its track as well, and re-acquire it as needed if its track quality drops or you shift attention to the high-risk target. This approach preserves safety by addressing the most dangerous situation first while avoiding losing sight of the other target.

Merging tracks would blur the identities and motion of each target, making it hard to assess relative motion and collision risk. Monitoring only one target leaves the second threat unseen, increasing the chance of a surprise collision. Address the higher-risk target first, rely on the higher-quality track for reliable guidance, and keep the other target under observation with re-acquisition as needed.
