美国空军和海军于1983年初开始联合研制一种从空中发射、具有昼夜巡航能力的反辐射导弹,命名为“默虹”,代号为AGM—136。研制该导弹的主承包商是诺思罗普公司,其次是得克萨斯仪器公司和雷锡恩公司等,分别承担导引头和制导系统的研制任务。 “默虹”反辐射导弹具有一对前翼,尾部有折迭式发动机吊架,它利用喷气发动机推进,可长时间地巡航在空中,实际上是一架小型无人机,射程达数百公里,能独立完成探测、摧毁敌方地面和空中的电磁辐射设备。“默虹”一进入目标区域,就进行巡航,一旦探测到雷达信号,便立即攻击。在攻击过程中,若敌方雷达关机,该导弹便爬高,并在对方雷达阵地上空巡航,等待时机,再次攻击。“默虹”的技术特点是:装有宽波段 In early 1983, the U.S. Air Force and the Navy began to jointly develop a anti-radiation missiles launched from the air and capable of cruising day and night, and named it “Mercury,” code-named AGM-136. The main contractor to develop the missile is Northrop, followed by Texas Instruments and Raytheon companies, respectively, to undertake the task of seeker and guidance system development. “Meihong” anti-radiation missile has a pair of front wings, the rear has a folding engine hanger, which uses jet engines to propel, long cruise in the air, is actually a small UAV, a range of hundreds Km, able to independently detect, destroy the enemy’s ground and air of electromagnetic radiation equipment. As soon as Mercury enters the target area, it cruises and attacks once the radar signal is detected. During the attack, if the enemy radar shuts down, the missile will climb high and cruise over the other radar position, waiting for the opportunity to attack again. “Meihong” technical characteristics are: equipped with a wide band
