摘要
使用微分求导法,得出相控阵雷达波束跃度,并通过其与相控阵雷达移相器的阵内移相量和半功率点波束宽度之间的关系,提出了一种移相器位数选取的标准,通过取不同的移相器位数对相控阵雷达波束覆盖程度的影响和仿真其雷达波束扫描方向图进行比较,验证了其合理性和适用性。
This paper elicits Phased Array Radar Beam Bound by using Differential Coefficient method, then, compares it with the connection between the measure of phase Shifter and the HPBW, and simultaneously puts forward a selecting standard of Phase Shifters＇digit. Finally, the paper analyzes the effect of different Phase Shifters＇ Digit on the Beam Coverage degree, imitates and compares the Pattern of Beam Scan, which validates the rationality and applicability of it.
