Aero‐Notes

Passive millimetre‐wave imaging may open a new, lifesaving vision window for military and commercial pilots caught in bad weather. A display on the instrument panel could perhaps let them see their surroundings during landing or take‐off even in very dense fog or thick cloud cover. The system could also simplify ground surveillance by airport controllers and give improved information on oil spills, snow cover, vegetation, etc., when used in a remote sensing mode. The technology is under development at TRW's Space & Technology Group, Redondo Beach, California.
