摘　　要：为了提升空间锥体目标突防能力,该文提出一种基于快慢时间域间歇采样转发干扰生成沿距离向及方位向分布的空间锥体ISAR群阵列方法。首先分析了双站情况下空间锥体目标ISAR像成像方法;针对线性调频波分析了快慢时间域间歇采样生成空间锥体ISAR群阵列的基本原理及其ISAR假目标分布特性。最后结合电磁仿真数据,分析了快慢时间域间隙采样参数对ISAR群阵列分布的影响,可为ISAR欺骗式干扰提供参考。In order to improve the penetration ability of the cone target, a method is proposed to generate the array ISAR distributed along the range and azimuth direction by the intermittent sampling repeater jamming in fast and slow time. The ISAR imaging method of the precession cone target under binary radar is analyzed; aimed at the linear frequency modulation continuous wave, the basic theory of the array ISAR generated by intermittent sampling repeater jamming in fast and slow time is analyzed, and the distribution character of the array ISAR false target is also analyzed. Finally, with the electromagnetic simulation data, the array ISAR,s distribution character influenced by the parameters of intermittent sampling repeater jamming in fast and slow time is discussed, which can provide reference for deception jamming for ISAR.
