| 摘 要： | 阐述了空间目标的雷达对抗措施,通过仿真研究了对抗条件下的空间中段目标ISAR成像与识别,分析了对抗手段对ISAR成像质量与识别性能的影响,指出对ISAR的二维压缩机理进行破坏是实施有效干扰的关键所在。仿真结果表明,通过对抗手段能有效降低ISAR的成像质量,破坏ISAR的识别性能。实验结果对于增强中段突防目标的突防能力有较重要的参考价值。

| Abstract: | Inverse synthetic aperture radar (ISAR) imaging of space target is an important approach to distinguishing a decoy. The countermeasures of space breakthrough target against ISAR are introduced. Radar imaging and identification of space target are simulated when countermeasures are used in midcourse. It is proposed that jamming two-dimension compress of ISAR is the key to combating ISAR successtuly, and the effect of countermeasures on imaging and identification is analyzed. Simulation results show that these countermeasures can degrade the ISAR image and weaken the identification capability of ISAR greatly. The experimental results are valuable for a space breakthrough target to improve its penetration ability. |
