Method and apparatus for detecting conditions in the atmosphere which are hazardous to flying aircraft and providing early warning to pilots or ground personnel. The method includes using a laser beam (34) and a coherent optical receiver (87) to optically sense sound waves (20) produced by those hazardous conditions and measuring the effect of those sound waves on the transmitted and received optical beams.
L'invention concerne un procédé et un dispositif destinés à détecter dans l'atmosphère des conditions dangereuses pour un aéronef propulsé, et à alerter rapidement des pilotes ou du personnel au sol. Ce procédé consiste à utiliser un faisceau laser (34) ainsi qu'un récepteur optique cohérent (87), afin de détecter de manière optique des ondes sonores (20) produites par ces conditions dangereuses et de mesurer l'effet de ces ondes sonores sur les faisceaux optiques émis et reçus.
