Deception against inverse synthetic aperture radar (ISAR) has been a topic of active research in electronic warfare. However, most of the studies mainly focus on producing one-dimensional deception, which is inadequate for two-dimensional imaging system like ISAR. Thus, in this letter, a joint two-dimensional ISAR deception based on frequency diverse array (FDA) and interrupted sampling is proposed. Compared with conventional phased-array (PA) and single-channel methods, FDA permits more degrees of freedom in producing range deception. Combined with interrupted sampling in the slow time domain, the proposed method is anticipated to produce a group of false targets in both range and cross-range directions. The benefit is easy to control the number and distribution of false targets with high efficiency and less computation burden. Simulation results verify the effectiveness of the proposed method.

通过频分集阵列对抗 ISAR 的联合二维欺骗


针对逆合成孔径雷达（ISAR）的欺骗一直是电子战领域活跃的研究课题。然而，大多数研究主要集中在产生一维欺骗，这对于ISAR这样的二维成像系统来说是不够的。因此，在这封信中，提出了一种基于频分阵列（FDA）和间断采样的联合二维ISAR欺骗。与传统的相控阵 (PA) 和单通道方法相比，FDA 在产生范围欺骗方面允许更大的自由度。结合慢时域的中断采样，所提出的方法预计会在距离和跨距离方向上产生一组虚假目标。这样做的好处是易于控制虚假目标的数量和分布，效率高，计算负担小。仿真结果验证了该方法的有效性。
