摘　　要：针对线性调频脉压雷达部分相参干扰信号参数设计的问题,在线性调频脉压雷达移频干扰和部分截取干扰的基础上,建立了一般化的线性调频脉压雷达部分相参干扰模型,通过理论推导和计算机仿真分析了部分相参干扰信号参数对功率损失、距离移动、脉压主瓣宽度等干扰性能的影响,分析结果表明:功率损失、脉压主瓣宽度由频移量和截取长度共同决定,随截取长度的增大而减小,随频移量的增大而增大;距离移动仅由频移量决定,与截取部分无关。分析结果为部分相参干扰信号参数设计提供了理论依据。To design the parameters of partial coherent jamming signal, a uniform model of partial coherent jam- ming to linear frequency modulation（LFM） pulse - compression radar is built based on frequency - shifting jam- ming and part copied jamming. Then, the influence of partial coherent jamming on power loss, difference of dis- tance and width of main lobe are analysed by theoretical derivation and computer simulation. The results show that the power loss and the width of main lobe increase with shift frequency increasing and reduce with the length of copied signal, the difference of distance is only presented by shift frequency. The resitlts provide theoretical reference for parameters design. Key words：
