Abstract

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.
