舰艇防御采用由箔条(雷达反射粒子云)组成的雷达假目标是一种比较新的技术。尽管早在四十年代末期人们已经认识到使用箔条的可能性,但是实际上这一领域内的所有进展是从1967年以来陆续取得的。在此以前由敌方雷达探测设备尤其是雷达制导的反舰导弹(ASM)造成的对水面舰艇威胁的严重性并不明显。 1967年以色列“埃拉特”号驱逐舰被“冥河”反舰导弹击沉这一事实使上述情况发生了 Naval defense uses a radar false target made of chaff (radar reflectivity particle cloud) is a relatively new technology. Although the possibility of using chaff has been recognized as early as the late 1940s, virtually all progress in this area has been made since 1967. Before this, the seriousness of the threat posed by surface ships by enemy radar detection equipment, especially radar-guided anti-ship missiles (ASMs), was not obvious. This happened in 1967, when the destroyer Eilat of Israel was sunk by the Styx anti-ship missile
