| 摘 要： | 针对组网雷达被单点运动辐射源干扰情况下的目标检测问题，本文利用目标多角度回波在传播延时、多普勒以及散射特性上存在差异的特点，设计了一种基于干扰延时、多普勒对齐的自适应干扰抑制算法。本文首先建立了单点运动辐射源干扰条件下的组网雷达信号模型，其次对抑制算法进行了详细介绍，最后通过典型场景的仿真分析验证了所提算法的抑制效果。仿真结果说明，所提算法可以充分利用目标在距离多普勒域的稀疏特性，实现干扰的有效抑制。

| Abstract: | In order to achieve effective target detection with a radar network interfered by a moving radiation source, an adaptive suppression method based on Delay-Doppler alignment is proposed in this paper. First of all, the signal model for large baseline radar network interfered by a moving radiation source is built. Secondly the adaptive suppression is introduced in detail. Finally, the effectiveness of the method is verified via the simulation of a typical example. The results shows that the proposed method can take advantage of the target sparsity in RD plane and realize effective interference suppression. |
