摘　　要：文章针对线性调频脉压雷达的信号特点,设计了几种典型的灵巧噪声干扰样式,例如移频丛伪复合干扰、延时叠加多假干扰、前端复制转发干扰和步进取样群集干扰等,并对此展开分析和仿真研究。仿真结果表明,灵巧噪声兼具相干噪声和欺骗干扰的特点,对脉冲压缩雷达具有较好的干扰效果。Aiming at the characteristics of LFM pulse compression radar signal,five typical smart noise jamming modes are designed,such as dense false target jamming based on frequency shift,smart jamming based on time-delay superposition,smart jamming based on frontier replication and smart jamming based on equal interval sampling in pulse,which are analyzed and simulated.The simulation results show that the smart noise has the characteristics of coherent noise and deceptive jamming,and has a good jamming effect on airborne multi-fuction pulse compression radar.
