ARPA data quality and speed come from the radar’s update rate and the tracking filter, not from how smoothly a target changes course. The system processes each radar sweep and uses measurements (range and bearing) to estimate position and motion. That processing workload is tied to how often sweeps occur and how the tracker operates, not to whether the target’s course changes gradually. Gradual course changes don’t inherently speed up processing, and while they can make corrections appear smoother, they don’t automatically make the information more accurate. Abrupt maneuvers, while challenging, provide more noticeable motion information for updating the track, but they likewise don’t guarantee faster processing—the update rate and the filter’s tuning determine accuracy. So the statement isn’t correct.
