...pilots zipping overhead who may not have time to analyze infrared images of their targets, which reveal the wooden husks below for what they are. Except, that is, when the decoys include heaters to simulate the infrared signature of, say, a tank engine, and perhaps crude transmitters to produce radar signals. A deluxe imitation tank from M.V.M. runs about $23,000, a lot cheaper than the real thing, which can cost $1 million or more...
...briefing was lengthy, packed with information and as candid as any the Bush Administration had yet given on the gulf war. But when General Colin Powell trotted out the visual aids last week, things got a bit fuzzy. One chart, showing the decline in Iraqi radar activity under allied bombing, was virtually devoid of numbers. Still, said Powell, the gist was accurate. "Trust me," he said. "Trust...
...secret of the Tomahawk's precision flying is a two-step guidance system. First, a radar altimeter compares the topography of key landmarks along the missile's flight path with detailed contour maps stored in its computer memory. Then, as the Tomahawk approaches its target, a small digital camera, acting as an electronic eye, compares the view from the nose cone with a library of images prepared from satellite photos. If the missile sees that it is even slightly off course, it makes adjustments...
That is not an easy task even for the most technologically sophisticated nation. A modern assault -- and the one on Iraq appears to have followed this pattern -- begins with an attack on the enemy's air-defense capabilities. Ground-hugging cruise missiles, flying too low for radar to detect easily, hit targets initially judged too dangerous for manned aircraft to handle. In the assault on Baghdad, some of the first blows came from Tomahawk cruise missiles fired by ships far out in the Persian Gulf. As the first explosions rocked the city, Iraqi antiaircraft fire was directed into...
...provide greater access to U.S. electronic-surveillance intelligence, concerned that the information might encourage the Israelis to strike Iraq. Although Shamir and Bush talked twice by phone last week, Shamir says "more coordination" is necessary. Other Israeli officials privately warn of a potential disaster once the region's radar screens fill up with blips heading for Iraq...
