What term describes radar indications of aircraft or objects that do not exist?

The term that accurately describes radar indications of aircraft or objects that do not exist is commonly referred to as "false returns." These are signals that appear on radar displays but do not correspond to real aircraft or objects. Such false returns can be caused by various factors, including ground interference, weather phenomena, or equipment malfunctions. Understanding this concept is essential for air traffic controllers to distinguish between actual aircraft and misleading signals, which can help in maintaining safe airspace management. The other options may hint at similar phenomena but do not fit the specific terminology widely accepted in aviation. For instance, phantom echoes may refer to specific instances of radar artifacts that suggest the presence of an object but do not necessarily define them as false objects or returns. Echo anomalies typically suggest a broader range of unusual radar behaviors and may not specifically pertain to non-existent targets. False targets is a close term but is less commonly used in official aviation terminology compared to "false returns."
