摘要:

相控阵雷达采用多通道工作方式后增加了自由度并提升了系统性能。针对雷达遇到的同步问题,提出一种相控阵雷达多通道同步方法。该方法首先采用同步触发方式对单个时钟芯片进行同步,然后对多个时钟芯片的同步信号进行精确延时调整,最后采用一种自适应采样窗口中心调节方法实现多个高速模数转换器的同步。将其应用于实际雷达产品,实测结果表明,该方法可有效实现相控阵雷达的多通道同步。

Abstract:

The multi-channel mode of phased array radar increases the degree of freedom and improves performance of the system. To solve the synchronization problem of the radar, a multi-channel synchronization method for phased array radar is proposed. It uses the synchronization trigger mode for single clock chip. The delay values of multiple synchronization signals of the clock chips are adjusted accurately. An adaptive sample window center adjustment method is proposed for multiple high speed analog to digital converters. This method is used for actual radar products. Test results have demonstrated the effectiveness of the approach to implement multi-channel synchronization for phased array radar.

Key words: multi-channel, synchronization, phased array radar, JESD204B standard, clock
