摘　　要：机载雷达空时自适应处理(STAP)技术利用空间和时间联合域滤波,最大限度地消除杂波和干扰。针对当前STAP雷达干扰存在的不足,提出了一种基于伪随机多普勒假目标干扰的STAP雷达干扰方法。首先建立了雷达STAP的信号模型,然后对伪随机多普勒假目标干扰的数学模型进行理论分析,最后仿真研究了伪随机多普勒假目标干扰的干扰效能,仿真结果表明,伪随机多普勒假目标干扰对STAP具有非常好的干扰效果。研究可以为STAP雷达的干扰设计提供一定的参考意义。The technology of space-time adaptive processing(STAP)for airborne radar utilizes spa-tial and temporal joint domain filtering to eliminate clutter and jamming to the maximum extent.Aiming at the shortcomings of current STAP radar jamming,this paper proposes an jamming method against STAP radar based on pseudorandom Doppler false target jamming.Firstly,the sig-nal model of radar STAP is established,and then the mathematical model of pseudorandom Doppler false target jamming is analyzed theoretically.Finally,the jamming effectiveness of pseud-orandom Doppler false target jamming is studied through simulation.The simulation results show that pseudorandom Doppler false target jamming has very good jamming effect on STAP technolo-gy.The research can provide some reference significance for the jamming design against STAP ra-dar.
