摘要
对拖曳式诱饵干扰机理进行详细分析的基础上,从目标与诱饵的空间特性角度出发,利用空间谱估计技术提出基于波束域的等距多目标超分辨方法,实现拖曳式诱饵和目标角度维分离。同时,考虑诱饵与目标信号的相干性,采用了Toeplitz矩阵近似化方法进行信号解相干。通过计算机仿真对算法的有效性进行了验证,同时仿真结果为后续进一步对抗拖曳式干扰提供了研究思路。
From the space characteristic of target and towed decoy,and the workflow of towed radar decoy interfering radar,a equidistant multi-target resolving technology is proposed based on the beam space DOA estimation,a separation of target and towed decoys is realized. Considering the coherence of signals, the proposed algorithm is used in the Toeplitz matrix transform method. Finally the validity of the proposed algorithm is verified by simulations and experiments,and further countering the towed decoy value of research ideas is provided.
