Methods, computer-readable media, and systems for externally cued aircraft warning and defense are disclosed. A surveillance system (110) may include a sensor field or array (114) and may include a processor system (116) that processes signals including acoustic signals received by the sensor array. Signals including acoustic signals are processed to determine the presence of indicia, including acoustic signatures, of known surface-to-air missiles (130) including man-portable air defense systems. When the presence of such surface- to-air missiles is indicated, a cue signal is sent to one or more countermeasure systems (144, 146, 150) that include one or more countermeasures such as chaff, expendable decoys and flares. The countermeasure systems may be ground-based or aircraft-based. The countermeasures are deployed in response to the cue signal. The surface-to-air missile may consequently be defeated.
L'invention concerne des procédés, des supports lisibles par la machine, et des systèmes pour l'alarme et la défense d'aéronefs par repérage externe. Un système de surveillance peut comprendre un champ ou réseau de détection et peut comprendre un système de traitement des signaux, y compris les signaux acoustiques reçus par le réseau de détection. On traite ces signaux, y compris les signaux acoustiques, pour déterminer la présence d'indices, y compris des signatures acoustiques, correspondant à des missiles sol-air connus, y compris les systèmes de défense antiaérienne portatifs. Lorsque la présence de ces missiles est établie, un signal de repérage est transmis à un ou plusieurs systèmes de contre-mesures comprenant une ou plusieurs contre-mesures, du type chaff, leurres consommables et leurres thermiques. Les systèmes de contre-mesures sont déployés en réponse au signal de repérage, ce qui permet vaincre le missile sol-air.
