This paper considers the situational awareness function associated with an Unmanned Aerial Vehicle (UAV) arriving at an uncontrolled airfield. Given no air traffic control service available within such a terminal area, the UAV needs to establish a good level of situation awareness by using its onboard sensors to detect and track other traffic aircraft. Comparing to existing works which mainly use sensor observations in the filtering process, this paper exploits the circuit flight rules to provide extra knowledge about the target behaviour. This is achieved by using the multiple models to describe the target motions in different flight phases and characterising the phase transition in a stochastic manner. Consequently, an interacting multiple model particle filter with state-dependent transition probabilities is developed to provide the required situation awareness function.
