A NEW SPATIAL-TEMPORAL PROCESSING FOR AIRBORNE RADARS
-
摘要: 本文针对机载侧面相控阵雷达的杂波谱特点,提出了一种基于列子阵结构的先时后空局域联合二维信号处理方法。文中对该方法的原理和性能作了较详细的讨论,并与其它两种方法作了比较,理论分析和计算机模拟均表明新方法的性能和容差能力较好,特别是在主杂波附近区域的改善因子有明显的提高。Abstract: A new partial joint-domain spatial-temproal adaptive processing with time-space configuration is proposed, based on the properties of clutter returns received by an airbore phased array radar on which a side phased array antenna is placed. The principle and performance of the propsoed processor are analyzed in detail, and compared with those of two other processors. Theoretical analysis and computer simulation results show the excellent performance of the processor, particularly when targets are close to mainlobe clutter.
