Abstract: A laser range finder (LRF) (20) is used to identify an aircraft (12) approaching a gate. The LRF (20) is directed at the aircraft (12), and from the echoes, a profile is derived and compared to known profiles. To distinguish among aircraft (12) with similar profiles, the LRF is directed at a volume in which a feature such as an engine is expected and at another volume in which the engine is not expected. The echoes from the two volumes are used to determine whether the engine is in its expected location. If so, the aircraft (12) is identified as the correct type and is allowed to dock at the gate (16). Otherwise, the aircraft (12) is stopped. The nose height can be used as yet another identifying criterion.
