摘要
天线通道一致性补偿测试对有源相控阵雷达非常重要。不同的补偿测试方法精度不同。文章分析了一次补偿方法的主要流程,设计了迭代补偿改进方法,并在天线样件上实测验证,有效甄别了异常通道,改善了副瓣电平0.7dB。
The uniformity offset measurement of antenna cells is most important for active phased-array. Different methods lead to different results. This paper presents the primary procedure of the once offset means. Further, an optimization way, iteration offset method, is also achieved. These methods are applied to a sample antenna. The results show that the optimization way can distinguis habnormal antenna cells and the sidelobe level is increased by 0.7 dB compared with foregone.
