| 摘 要： | 本文针对机载预警雷达的杂波环境，分析了杂波数据的非平稳性，由此提出在距离上分段实现空时二维自适应处理（STAP）的方法，并通过分析杂波于空间的距离来确定分段的方法。在同时考虑实时性和处理器性能的前提下，给出了一种自适应权值计算的递推算法。理论分析和计算机仿真结果均表明，本文提出的分段递推算法是有效的。

| Abstract: | In this paper the non-stationary characteristics of clutter echoes is analyzed in the clutter circumstance of airborne early warning (AEW) radar And a novel 2-D (two dimension) space-time adaptive nethod is presented, which is segmented in the distance The segment method is determined by analyzing the distance of neighboring clutter subspace. A recursive algorithm of adaptive weight is presented with considering the real-time implementation and the performance of processor. Theoretical analsis and computer simulation results show that the propsed apporach is effective. |
