摘要

传统上，时空自适应处理(STAP)主要应用于均匀线性阵列。然而，当考虑到整个雷达系统时，电子扫描的圆形阵列具有优势:更好地结合了均匀和连续的角度和时间覆盖，并且由于不需要旋转而机械简单。关于圆形数组的悬而未决的问题是它们对STAP的适用性。研究表明，对于机载预警任务，圆形阵列确实是兼容STAP的。然而，从STAP的角度来看，与ULA相比，性能可能会有一点损失。在选择和实现STAP算法时要小心，大多数退化是在近距离，目标回报相对较强。在远距离上，性能几乎没有受到影响。

Circular array STAP

Traditionally, space-time adaptive processing (STAP) has been applied to uniform linear arrays (ULAs). However, when considering the overall radar system, electronically scanned circular arrays have advantages: a better combination of even and continual angular and temporal coverage, and mechanical simplicity because it does not need to rotate. The unanswered question about circular arrays is their suitability for STAP. This paper shows that for the airborne early warning (AEW) mission, circular arrays are indeed STAP compatible. However, from the STAP perspective there may be a small loss in performance when compared to a ULA. With some care in the choice and implementation of the STAP algorithm the majority of the degradation is at close ranges, where the target returns are relatively strong. At long ranges the performance is barely affected.
