具有抽头延时器的天线阵抗宽带干扰性能分析与定量计算

Analysis and Calculation on the Performance for Anti-Wideband Interference of an Adaptive Array with Tapped Delay-Line Processing

本文计算并分析了具有抽头延时器的自适应天线阵的性能,作出了阵列波束图、预定频段目标和干扰信号的频率传输图,以及目标和干扰信号偏离预定方向时的阵列增益变化图。结果表明,在干扰信号方向上和带宽内,系统具有准确、有效的抑制能力。本文还提供了G与SNR及INR的关系数据表,对雷达设计者有一定的参考价值。

The performanee of an adaptive array with tapped delay-line processing is analyzed and calculated in this paper.The curves of the array beam pattern,target and interference signal frequency transfers in the specified band are given along wich the gain variation of the array when the target and interference signal deviate from the desired direction.It is Shown that the array is capable of restraining the interference effectively in its direction and bandwidth.The data tables of G versus SNR and INR given in the paper are valuable for radar designer.
