A method for classifying aircraft behaviour comprises receiving S100 aircraft data from an aircraft; determining S102 whether the received aircraft data comprises identification information for the aircraft; in response to a determination that the received aircraft data comprises identification information, using said identification information to classify the behaviour of the aircraft; and in response to a determination that the received aircraft data does not comprise identification information, obtaining the position of the aircraft and comparing the obtained position to an expected route for the aircraft to classify the behaviour of the aircraft. If an aircraft identity is received then it may be checked as to whether it is a duplicate S104 of another received identity (spoofed). The identity also may be checked whether it corresponds to a known flight path S108, or flight number S106. The radar cross section of the aircraft may be compared to that expected from the aircraft type S113. If any of the checks are failed then an alert S114 may be generated to flag the aircraft as suspicious. The method may be implemented as part of an IFF system.
