单脉冲雷达导引头抗噪声干扰性能分析与验证

噪声干扰是雷达导引头需要对付的主要干扰形式之一。在压制式噪声干扰下,导引头由主动工作模式转为向干扰源寻的(HOJ)的被动工作模式,单脉冲雷达导引头可以从噪声干扰中提取出角跟踪误差信号,保持对目标稳定跟踪。但是在强噪声干扰下,导引头接收机处于饱和状态,失调角及测角方差恶化,从而使其不再具有任何利用价值,必须采取措施加以解决。

Analysis and Verification of Antinoise Jamming Capability for the Monopulse Radar Seeker

Noise jammer is one of the primary jamming that radar seekers have to antagonize.Under the oppressive noise jamming,the seeker turns into the passive working mode of Homing on Jamming(HOJ)from the initiative working mode.Monopulse radar seeker picks up the erro signal of the angle tracking,thereby,the seeker could track the target steady.But once the seeker is under a strong noise jamming,the receiver of the seeker becomes saturated,and the maladjusted angle as well as the variance of angle measure become so worse that cannot make any use,so it's important to find some way to solve the problem.
