| 摘 要： | 从逆合成孔径雷达运动补偿的角度对ISAR成像的干扰机理进行了理论分析,并进行了基于ISAR回波真实数据的仿真实验。理论分析和仿真结果表明,只要施加的干扰信号使得运动补偿过程中相邻距离像复包络的相关函数最大值出现误判,就会有效地使ISAR成像失真。然后,将ISAR与普通脉压雷达、SAR的抗压制干扰能力进行了对比,结果表明由于ISAR成像必须经过运动补偿处理,其抗压制干扰能力相对较差。

| Abstract: | Through motion compensation of Inverse Synthetic Aperture Radar(ISAR), the jamming mechanism of ISAR is analyzed and simulated. The results show the imaging of ISAR will be distorted effectively if the maximum value of the complex envelope correlation function of neighbor range images is false alarm. Furthermore, the comparison of anti-jamming ability among ISAR, SAR and linear frequency-modulated radar shows that the anti-jamming ability of ISAR is worse because it needs motion compensation before imaging. |
