...satisfied to snag speeders with only prowl cars and radar traps, the Florida highway patrol has a three-plane air force. At a couple of dozen locations, Florida highways are festooned with white stripes a quarter-mile apart. Orbiting at altitudes of 800 ft. to 1,500 ft., a trooper in a Piper Cub can clock cars whizzing by below. If his stop watch says a car has raced over the quarter-mile stretch too fast (less than 12.8 sec. in a 70-m.p.h. zone), the flying cop radios a cruiser on the ground to make the arrest...
...highway patrol's dismay, Florida's Attorney General Earl Faircloth last week went far beyond Williams' analysis in a ruling that suspended the use of radar and electronic timers as well as airplanes. Under current Florida law, said Faircloth, the information provided by all these gadgets is hearsay evidence and is therefore inadmissible. To restore electronic enforcement, Faircloth urged the state legislature to legalize such information by classifying it as prima-facie evidence. If the legislature agrees, Florida courts will be able to accept the evidence as conclusive whenever the defendant fails to rebut...
...prima-facie technique has been adopted by legislatures or courts in many of the 45 states where police now use radar. Joining four other states...
Cones, Cylinders & Spheres. So many satellite analyses have been made that RCA is now compiling a catalog of the radar signatures of known satellites. Scientists working for the Air Force have also been bouncing radar signals off an assortment of complex, spacecraftlike shapes on test ranges to establish their characteristic radar patterns. Even more important, they are deriving a series of mathematical formulas that match radar signatures to specific satellite shapes. These, they hope, can some day be used to program a computer to recognize and identify radar signatures more quickly than human operators. Their work is proceeding slowly. "Once...
Despite the math problems, the Air Force is determined to develop computerized RSA, or at least a combination of human analysts and computers, as quickly as possible. In the event of a nuclear war there would be little time for human analysts to leaf through a radar signature catalog in an effort to differentiate between an incoming ICBM warhead and its decoys. Only a computer could spot the authentic warhead radar signature quickly enough to order its interception and destruction by defending missiles...
