摘要
间歇采样转发干扰是针对相参雷达一种有效的干扰方法,它利用脉压雷达匹配滤波特性,能够对雷达形成假目标干扰。首先分析了间歇采样转发干扰方法,指出了间歇采样转发干扰的不足之处,即脉压后干扰能量损失和假目标分布均匀,进而提出了间歇采样灵巧干扰方法,新方法形成的假目标分布不均匀,使得雷达识别真假目标可能性大大降低,仿真实验验证了新干扰方法的有效性。
Interrupted sampling and repeater jamming is an effective method against coherent radar It can generate false target jamming by means of matched filter character. Interrupted sampling and repeater jamming is analyzed first, and then the shortage of this jamming method is pointed out ： power lost using pulse compression and regular distance of false target jamming. To overcome this shortage, the interrupted sampling smart jamming method is proposed. This new method can generate asymmetrical false target, so the recognition of radar can be reduced deeply. Simulation results prove the validity of the new jamming method.
