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。
Aiming at the clutter environment of airborne early warning radar, this paper analyzes the nonstationarity of clutter data, and proposes a method to realize Space-Time Two-Dimensional Adaptive Processing (STAP) on the distance by analyzing the clutter in space The distance to determine the method of segmentation. Under the premise of considering both real-time and processor performance, a recursive algorithm of adaptive weight calculation is given. Theoretical analysis and computer simulation results show that the proposed segmentation recursive algorithm is effective.
