ABSTRACT:
The different advantageous embodiments provide a method and apparatus for detecting an aircraft. The different advantageous embodiments may provide a method for detecting an acoustic emission emitted by the aircraft using a number of acoustic sensors to form a detected acoustic emission. The aircraft may be identified from the detected acoustic emission to form an identified aircraft. A bearing may be estimated for the identified aircraft using the detected acoustic emission.
