In an interferometric array this occurs when some elements of the array provide information that an object exists while other elements deny the existence of that object. It can only be considered a Ghost if the different perspectives of the array elements can be ruled out as an explanation of the anomaly. The most common cause of Interferometric Ghosts is data tampering.
It is unknown how many interferometric images have been tampered with by high level AIs or altered by viruses. However, the total amount of tampered data can be estimated by the Aookxenz equation in which the total tampered interferometric data is directly proportional to the number of interferometric ghosts. This number tends to vary in direct proportion the the perceived "interest" of a given data set.
