反舰导弹、特别是掠海飞行导弹对水面舰只的威胁已大大超过传统的重型火炮、鱼雷等海战武器。随着超音速导弹的出现,这种威胁变得尤为严重。这种武器几乎可由任何平台发射,如水面舰只、潜艇、飞机和岸上炮台等。因此,各国海军都在寻求可以保护其舰只免受掠海飞行导弹袭击的防御系统。法国的Thomson-CSF公司十多年前开始联合研制响尾蛇导弹系统。这种导弹最初是用来拦截约五十米高度低空飞行飞机的。Thom-son公司进一步将这种导弹发展成为对付掠海飞行导弹的有效武器。由于不管多好的雷达制导系统,当接近目标时,都要受到海面杂波的 The threat posed by anti-ship missiles, especially those flying the sea-guided missiles, to surface ships has surpassed that of traditional heavy artillery, torpedoes and other naval weapons. With the emergence of supersonic missiles, this threat has become even more serious. Such weapons can be launched on almost any platform, such as surface ships, submarines, aircraft and shore forts. As a result, navies of all nations are seeking defensive systems that can protect their ships from attack by sea-grazing missiles. France’s Thomson-CSF company started a joint rattlesnake missile system more than a decade ago. This missile was originally used to intercept a low altitude flight of about 50 meters. Thompson further developed the missile into an effective weapon against swept sea flying missiles. No matter how good the radar guidance system, when approaching the target, are subject to clutter
