1. A method for detecting an aircraft, the method comprising:
- detecting, by one or more processors, an acoustic emission emitted by the aircraft using a number of acoustic sensors to form detected acoustic emission;
identifying the aircraft from the detected acoustic emission to form an identified aircraft;
estimating a bearing for the identified aircraft using the detected acoustic emission; and
predicting, before a movement of the identified aircraft from a first position to a second position, a potential movement of the identified aircraft from the first position to the second position using the detected acoustic emission by identifying a change in the detected acoustic emission from a previous detected acoustic emission as a change from an idle state of the engine to a run up state of the engine.
