...parliament that the 1979 invasion of Afghanistan had "blatantly violated" the law. By doing so, he implied that events like the 1956 Hungarian crackdown and the 1968 Czechoslovakian invasion would not recur. In addition, with a candor rare even in the West, Shevardnadze said of the controversial Krasnoyarsk radar station in Siberia: "Let's admit that this monstrosity the size of the Egyptian pyramid has been sitting there in direct violation of the ABM treaty." (His fealty to the treaty was in part motivated by a desire to drive a stake through America's SDI missile-defense program...
...past glory, radar is facing its most perilous assault ever. All the major military powers are working on stealth technologies designed to defeat radar. The U.S. Air Force's new B-2 Stealth bomber, for example, is supposedly almost invisible to radar because its sleek shape and special composite construction tend to absorb rather than reflect electronic signals. The same techniques will soon be used to introduce stealth missiles, ships, satellites and tanks. Moreover, military designers have developed missiles and other weapons that can zero in on electronic signals and thus destroy the ships and planes carrying radar. Faced with...
...weapons of modern warfare, none is more venerable than radar. The seemingly magical technology that enables planes, ships and artillery units to spot the enemy from afar has made the difference between defeat and victory in many a battle. In a Nova TV episode called Echoes of War, which was shown on the Public Broadcasting System last week, radar was hailed as the military's unsung hero of World War II. As physicist I.I. Rabi once recalled, "Maybe we could have won it without the atomic bomb . . . but without radar we could have lost...
...issue is of utmost importance to the U.S. armed forces. Virtually all American warplanes use radar, and many costly weapons systems, from the Navy's Aegis system to the Army's Patriot missile, are heavily reliant on the technology. By one estimate, about a quarter of U.S. military investment is radar related. If heavy use of radar becomes questionable, the Pentagon will have to rethink its whole strategy and allocation of resources...
...development of radar (short for radio detection and ranging) applications in the U.S. stemmed from the accidental discovery in 1922 that a ship moving between a radio transmitter and receiver interfered with the signals. The technology came into its own in World War II, when it progressed rapidly from a crude early-warning system barely able to locate ships and aircraft to a sophisticated electronic eye that can spot the periscope of a submerged submarine. Radar works because electronic signals bounce off objects, just as a voice is reflected by walls or buildings. Radar transmits radio waves and "listens...
