Design of Beam Steering in Ship-borne Phased Array Radar Based on Serial RapidIO

为了提高舰载相控阵雷达波束指向捷变能力,设计了一种分布式波控系统,其中传输方式采用串行RapidIO,波控主机采用PowerPC矢量运算处理器,子阵运算模块为FPGA。重点推导了舰载相控阵雷达波控码的公式,实现了RapidIO的初始化编程,以及波控主机的波控任务编程。测试波控码的计算和RapidIO通信时间,设计方案能够满足舰载相控阵雷达的波束切换时间指标。

In order to improve the beam pointing agility of ship-borne phased array radar, we design a distributed beam steering system, in which transmission mode is the serial RapidIO, beam steering PC is PowerPC vector arithmetic processor, sub-array computing module is FPGA. The focal points of the full text are expressions deduction of beam steering code and programming of RapidIO initialization and beam steering tasks. The time test about the calculation of beam steering code and RapidIO communication proves that the design scheme can satisfy the beam conversion time index of ship-borne phased array radar.
