现代隐身技术始于 1 975年 ,它所带来的革新性变化将影响着后来的作战飞机设计技术 ,并且推广到导弹、潜艇、舰艇、战车等领域。美国发展隐身技术的同时 ,也在不断地改进对目标特征 ,即雷达截面积 (ＲＣＳ)的测试技术 ,据报道 ,美国的一些飞机制造厂商的内外场测试场所 ,已能测 Modern stealth technology began in 1975, and the revolutionary changes it brought will affect later combat aircraft design techniques and be extended to such fields as missiles, submarines, ships and tanks. While stealthy technology is being developed in the United States, it is also constantly improving its testing of the target characteristics, ie, the RCS. It is reported that some aircraft manufacturers in the United States have been able to test the internal and external test sites
