| 摘 要： | 针对线性调频脉冲压缩雷达,基于信号时域采样原理提出了一种新的灵巧噪声信号--参差间隔采样干扰信号.理论分析表明,干扰信号经线性调频脉压网络处理后,在目标回波前后一定距离范围内形成了假目标群,通过调整采样方波的脉宽、参差重复周期和调制相位,可以实现假目标幅度、数量和空间分布的控制.仿真实验给出了参差间隔采样信号的干扰效果,验证了理论分析的正确性.

| Abstract: | In order to counter LFM pulse compression radar,a new smart noise called staggered interval sampling signal is proposed based on time sampling. Theoretical analysis shows that the jamming output is a group of false targets which surround the true target within definite distance range. The amplitude,the amount and distribution of false targets can be controlled by altering the pulse width,the staggered interval and phase modulation of sampling signal. The simulation shows the jamming effect and verifies the ... |
