中文摘要：
针对机载多输入多输出雷达杂波分布呈现空时耦合特性,该文提出了一种新的空时2维脉冲相消杂波抑制方法,通过利用雷达参数以及载机速度可以确定杂波分布轨迹这一先验信息,设计出一种简单有效的空时2维脉冲相消器,作为空时自适应处理（STAP）的杂波预滤波处理方法,进一步提高目标的检测性能。试验结果表明,该方法可以较为灵活地根据不同阵列结构来构造,不受布阵方式的限制,同时对于高速运动目标的检测也较为有效。
英文摘要：
The spectrum of the clutter is spatially-temporally coupled in the airborne MIMO radar. Based on the knowledge that the location of the ground clutter in angle-Doppler domain is mainly dependent on the velocity of the airplane and the radar parameters, a novel two dimensional pulse-to-pulse canceller is designed to suppress the clutter signals more efficiently. As a pre-filtering tool before the conventional Moving Target Indication （MTI） and the sub-optimal dimension-reduced Spatial-Temporal Adaptive Processing （STAP） algorithms, the method can enhance the performance of moving target detection. The experimental results demonstrate that the proposed pre-filtering approach can effectively suppress the clutter and can be flexibly constructed according to different array configurations. Moreover, the proposed method can gain a better performance for detecting the high speed movirLg target.
