| 摘 要： | 针对机载MIMO雷达杂波空时耦合的特性,提出了一种应用于机载MIMO雷达的空时杂波块对消器。利用MIMO雷达接收杂波的多普勒相位和空域接收相位之间的关系,设计系数矩阵来对消杂波,后续级联空时自适应处理方法能进一步抑制杂波和提高动目标检测性能。仿真实验表明,该杂波块对消器能对正侧视和非正侧视机载MIMO雷达均有较好的杂波抑制能力,从而进一步提高了后续空时自适应处理算法的动目标检测性能。

| Abstract: | A space-time clutter block canceller (STCBC) applied to the MIMO radar is proposed.The equivalence between the spatial domain and the temporal domain information is exploited to make a cancellation between the clutter blocks by designing a coefficient matrix.The performance of following space-time adaptive processing (STAP) algorithms can also be enhanced.The simulation experiment shows that this method can effectively suppress the clutter in side-looking and non-side-looking airborne MIMO radar,and can further improve the moving target detection capability. |
