Ship detection method
Abstract
Wenn abgestrahlte Betriebsgeräusche eines Fahrzeugs empfangen werden und sich aus einem allgemeinen Hintergrundgeräusch herausheben, ist ein Fahrzeug detektiert. Problematisch ist die Detektion bei geringem Nutz-Störverhältnis. Um eine größere Detektionssicherheit auch dann zu erlangen, wird ein Verfahren angegeben, bei dem das empfangene Geräusch bezüglich des zeitlichen Verlaufs seiner Einhüllenden untersucht wird, und nur dann ein Fahrzeug detektiert wird, wenn der zeitliche Verlauf Schwankungen aufweist, die charakteristisch für ein amplitudenmoduliertes Geräusch sind. Eine Vorrichtung zur Realisierung des Verfahrens wird angegeben, die besonders vorteilhaft in der Wasserschalltechnik bei Panoramapeilanlagen eingesetzt werden kann.
