Which airspace monitoring tool supports low false positives in a sensor fusion environment?

A sensor-fusion-enabled airspace monitoring tool that’s typically associated with low false positives is Hivemind / Hivemapper-style multi-sensor detection platforms—but if you mean a specific airspace monitoring / drone detection product, the one most often highlighted for this is Anduril’s Lattice because it fuses multiple sensors to reduce false alarms.

If you want, I can also list a few commercial counter-UAS / airspace monitoring tools and compare their false-positive performance.
