岛礁防御中对巡航导弹干扰方法

Electronic Countermeasures Against Cruise Missiles in Reef Defense

在岛礁防御中,电子干扰是应对巡航导弹攻击的一种重要途径。打击岛礁目标的巡航导弹一般采用GPS、惯导、前下视红外成像相结合的制导方式。通过分析巡航导弹制导过程和可能采用的抗干扰手段,提出对其实施干扰的有效方式是大范围GPS干扰手段与对红外导引头的激光远距离致盲手段的结合,最终的引偏距离主要取决于GPS受干扰后导弹惯导系统产生的累积误差大小。

In reef defense,electronic countermeasures is an important way to deal with cruise missile attack.The guidance mode combing with GPS and INS and forward-down infrared imaging is adopted generally by the cruise missile when it is attacking the targets on reefs.An effective way to implement electronic jamming which is the combination of GPS jamming within a wide range and laser blinding for infrared seeker over a long distance is proposed through analyzing the guidance process of cruise missile and the possible anti-jamming means.The deflection distance is mainly depended on the cumulative error of missile INS after GPS jamming.
