| 摘 要： | 该文根据欺骗干扰原理，将动目标检测技术引入到对欺骗干扰目标的检测中，提出了沿航迹双天线干涉对消检测欺骗干扰的方法。并在空域对消技术的基础上，进一步提出了跨航迹双天线干涉对消检测欺骗干扰的方法。文中分别对这两种检测方法中的空域对消技术做了详细的分析，对检测方法的适用性进行了讨论。最后利用点目标进行了仿真实验，结果表明这两种方法都能对欺骗干扰目标进行有效的检测与识别。

| Abstract: | In this paper, a deception jamming detection scheme derived from moving target detection is proposed, which is based on dual-aperture antenna along-track interferometric SAR. Another new scheme of deception jamming detection is also investigated on the basis of dual-aperture antenna cross-track interferometric cancellation. Both schemes are discussed respectively on its spatial cancellation algorithm and applicability in detail, and demonstrated effectively with point target simulation in detecting deception jamming. |
