马可尼雷达系统公司研制出一种超视距雷达,并声称,将使防空体系发生彻底变革。该雷达可防止敌机利用地球曲面躲避探测,这是福克兰群岛战争中所采用的一种战术。这种新型雷达发射短波无线电信号,借助海水含盐的特点,沿地球表面传播,目标回波则沿相同轨迹返回。据称,低空飞行的飞机、掠海飞行的巡航导弹以及舰船,将在 Marconi Radar Systems has developed an OTH radar and claims that it will revolutionize its air defense system. The radar prevents enemy planes from using the Earth’s surface to evade detection, a tactic used in the Falkland Islands war. The new radar transmits shortwave radio signals that travel along the Earth’s surface with the salinity of seawater and return the target echoes along the same trajectory. Allegedly, low-flying aircraft, swept the sea flying cruise missiles and ships will be
