当美、英空军进攻伊拉克时,他们准备了最先进的防御系统来使飞机免于遭受敌军防空导弹的打击。在这些设备中,最重要的就是拖曳式诱标,我们来看看这种最先进的科技是怎样反击无处不在的防空导弹(SAM)的威胁。要在防空雷达系统中保护飞机,有两种基本方法,其中一种就是主动式电子干扰,另一种就是让飞机“隐藏”起来,或二者兼用,来试图掩盖飞机的存在,或使其相信飞机是在别的地方。这可以通过使用拖曳式诱标来实现。从上世纪70年代末开始,西方电子作战系统的设计者们就面临一个严峻的问题——如何抵抗采用单脉冲雷达制导的新型苏联地空和空空导弹。从技术角度来讲,对于那些不够灵活的欺骗干扰信号,这些雷达是战无不胜的。这种雷达装有电子回路,用来滤出无价值的信号,而且新型导弹还能追踪出干扰信号的源头,这就给战斗机带来更大的威胁。
When the United States and British air forces attacked Iraq, they prepared state-of-the-art defense systems to protect the aircraft from enemy air defense missiles. The most important of these devices is drag-and-drop, and let's see how this state-of-the-art technology counteracts the ubiquitous threat of SAM. There are two basic ways to protect an aircraft in an air-defense radar system, one of which is active electronic interference and the other is to try to conceal the presence of the aircraft by “hiding” the aircraft or both Make it believe the airplane is somewhere else. This can be achieved by using drag-and-drop cues. Since the late 1970s, designers of western electronic warfare systems have faced a serious problem of how to resist the new Soviet air-to-air and surface-to-air missiles guided by monopulse radar. From a technical point of view, these radars are invincible to those cheating signals that are not flexible enough. The radar is equipped with an electronic circuit to filter out worthless signals, and the new missiles track the source of interference signals, posing a greater threat to fighters.
