The controller received multiple conflict alerts over a period of ten minutes. The aircraft was squawking 2244; and the tagged target conflicted repeatedly with a 2244 beacon code in close proximity. Company confirmed that the aircraft was ADSB equipped. These types of conflicts are a recurring issue and have increased in number since the introduction of FUSION. Erroneous conflict alerts (i.e.; aircraft conflicting with themselves) are distracting to controllers and may draw attention and resources away from more important tasks; causing potential safety hazards.Update MEARTS software and/or hardware to reduce or eliminate erroneous conflict alerts.
The reporter describes an instance of an aircraft conflict alert activating when there is no traffic. Reporter stated this is a common problem at facilities that have upgraded to FUSION radar display software.
