<p>A system (24) for detecting an air disturbance in front of an aircraft (10) has a controller (26) that is coupled to an image detector (40). Image detector (40) generates an image signal corresponding to heated air in front of the aircraft (10). The air in front of the aircraft (10) is heated by direct high energy beams such as microwave beams (16, 18) from a respective microwave antenna (12, 14). By monitoring the image, the presence of an air disturbance may be determined. Position adjusters (30, 32) may be used to adjust the position of the beams (16, 18) by controlling the position of antennas (12, 14). The position of the beam is preferably maintained a predetermined distance (d) in front of the aircraft (10) so that an evasive maneuver may be performed. <IMAGE></p> |
