-
摘要: 本文提出了一种便于工程实际实现的机载雷达空时二维自适应处理方法,其特点为在主杂波区增加辅助阵元。经理论分析和计算机模拟表明,这种方法可以通过空时两方面有效地抑制地杂波,获得优良的系统性能,同时运算量小,实现方便,具有工程应用前景。同时本文还对在主杂波区增加辅助波束的方法进行了分析研究。Abstract: A convenient implementation approach of space-time adaptive processing for airborne radar has been proposed, which is added by some auxiliary array elements in the area of main-lobe clutter. It is of practical use for its small computational load. Since this approach possesses the ideal performance in the area of main-lobe clutter so that it is adequate to the phased array radar which the array antenna is placed on the aircraft by non-facade side. In addition, the approach which is added by some auxiliary beams in the area of main-lobe clutter has been discussed.
