摘要
针对相控阵系统相位一致性要求高,阵元数量巨大,相位校准与测试困难的问题,设计了一种自动补偿相位的波束控制系统,系统基于CAN总线通信,采用FPGA和单片机作为补偿算法核心,具有结构简单、可靠性高、波控速度快的特点。
Phased array system has large number of array elements,it has high requirements for the phase consistency.So to solve the problem of phase calibration and testing,a beam steering system using automatic phase compensation is designed.Based on CAN bus communication,the system use FPGA and single chip microcomputer as the hardware core of compensation algorithm.It has the characteristics of simple structure,high reliability and fast wave control speed.
