摘要
本文在分析矩形平面相控阵天线方向图特点的基础上,研究了相控阵机载预警雷达的时空二维杂波谱特性。着重研究了侧面阵天线的杂波谱特点,并与机扫天线的情况作了比较;最后讨论了前后阵天线的杂波谱结构。
Based on the pattern characteristies of planar phased arrays,this paper studies the properties of temporal-spatial 2-D clutter spectrum of AEW radar with the phased arrays,with the emphasis on sidemounted phased arrays.A comparison between electronical and mechanical scannings is then made.Finally, the spectrum structure of the forward and after arrays is briefly discussed.
