摘要
导弹防御系统的地基X波段雷达和海基X波段雷达是进行目标识别的主要传感器,它们只有在探测到目标以后才能通过记录目标的相关特性,进行目标识别。由于雷达探测的方向不同,探测到的目标散射截面也不同,因此,在导弹突防过程中,可通过调整弹头的飞行姿态,改变雷达探测方位,从而最大限度地减小目标散射截面,最终影响雷达识别目标的效果。
Terrestrial-based and sea-based X-band radars of missile defense system are the prime sensors of target identification. They can memorize the related targets signature so as to discriminate them after the radar detecting the targets. Because of the difference of azimuth of radar detection, the RCS of targets are different, during the missile breaking through defense, the attitude of warhead can be controlled to make the azimuth of radar detection keep some angle, and make RCS of target minimum, so as to affect the radar identification.
