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 analysis of the characteristics of the rectangular planar phased array antenna pattern, the space-time two-dimensional hybrid spectral characteristics of the phased array airborne early warning radar are studied. The characteristics of the clutter spectrum of the side array antenna are emphatically studied, and compared with the case of the machine sweep antenna. Finally, the structure of the clutter spectrum of the front and back array antennas is discussed.
