摘　　要：随着相控阵天线在卫星通信、侦察等领域中的广泛应用,在轨动态方向图综合的需求逐渐凸显。从经典的Woodward-Lawson采样法出发,深入分析了Woodward-Lawson采样法的副瓣特性,总结了Woodward-Lawson采样法的改进措施,并提出了从一维线阵推广到二维阵列进行波束赋形的方法,其处理流程简单、计算量较小,适于星载相控阵的在轨赋形应用。Due to the progressively massive application of phased array antennas in satellite communication and reconnaissance,the need of on-orbit dynamic pattern synthesis is arising.From the classical Woodward-Lawson sampling method,deep analyzation on the sidelobe characteristics so as the summarization on the improvement measures of it are made in this paper.Meanwhile,the method of pattern synthesis from one-dimensional linear array to two-dimensional array is proposed,which is suitable for on-orbit beamforming application of spaceborne phased array for its simplicity of implementation and small calculation consumption.
