Raytheon's airway radars, which have revolving antennas 40 ft. wide, are modeled after equipment used in military air-warning networks. Raytheon engineers are confident that they can track large commercial airliners, flying 70,000 ft. up, 200 miles away. When rain clouds cut off the view of a distant airliner, the radar can switch to a special "circularly polarized" wave that is reflected differently by spherical raindrops and the metal surfaces of wings and fuselage. This gimmick makes an airliner visible even behind a rain cloud. Another gimmick makes the radar blind to all objects that...
...traffic. Jetliners use so much fuel while flying slowly that they cannot hang around an airport waiting for a chance to land. The U.S. Civil Aeronautics Administration has not contracted so far for a complete long-ranch system, but the President's budget calls for radar control of air traffic in the congested triangle bounded by Chicago, Boston and Norfolk...
...Political Radar. There were rumors that some important Stevenson supporters were about to switch to Kefauver, but no real evidence of major changes. The only noteworthy shift came in Stevenson...
...home. The Icelandic Althing (Parliament) passed a resolution urging the withdrawal of all foreign troops, meaning the 5,000 U.S. soldiers and airmen who have been stationed in unarmed Iceland-at its own request-since 1951. Pulling out would deprive the U.S. of an important early-warning radar establishment halfway between New York and Moscow, and the strategic $100 million Keflavik air base, where a squadron of F-89s is stationed...
...study will be made by radar astronomy, closely allied to the radio astronomy so prominent in the Observatory's recent work. The distincton between this project and radio astronomy lies in the fact that the radio waves are sent up from the ground first, and not emitted by the subjects--in this case, the meteors...
