摘要
波束阵列的畸变对测向精度等指标有很大影响。简述了二维多波束系统的波束形成方法,重点分析了二维多波束阵列的畸变情况,对二维多波束测向原理进行了讨论,提出了二维多波束阵列畸变的校正方法。
The direction finding accuracy of the EW system is affected by the distortions. The beam- forming and distortion of two-dimension multi-beam system is introduced mainly, and the principle of the two-dimension multi-beam amplitude-comparison direction finding is also introduced. Some cor- rection ways for the distortions are presented.
