摘要

摘要: 欺骗干扰不仅会使雷达无法分辨真实目标与虚假目标，还会对真实目标的参数估计精度和跟踪性能产生极大影响。针对机载分布式雷达中的欺骗干扰鉴别问题，该文提出了一种基于相位起伏的欺骗干扰鉴别方法。该方法首先对机载分布式雷达系统中影响回波信号相位的同步误差进行校正；然后对接收到的多站回波进行精细化处理以获取多站目标散射相位矢量；最后根据真假目标散射特性差异，采用相位矢量的起伏方差鉴别真假目标。所提方法可以增强机载分布式雷达系统在复杂电磁环境中的抗干扰性能，仿真结果验证了该方法的有效性。

Abstract: Deception jamming not only prevents radars from distinguishing real targets from false ones but also significantly degrades the parameter estimation accuracy and tracking performance of real targets. To address the deception jamming identification issue in airborne distributed radar systems, this paper proposes a discrimination method based on phase fluctuation. The method first corrects synchronization errors affecting the echo signal phase in airborne distributed radar systems. Subsequently, refined processing is applied to the received multi-station echoes to extract multi-station target scattering phase vectors. Finally, leveraging differences in scattering characteristics between real and false targets, the fluctuation variance of phase vectors is utilized to discriminate between them. The proposed method enhances the anti-jamming performance of airborne distributed radar systems in complex electromagnetic environments, and simulation results validate its effectiveness.
