SPI(同步串行接口 )技术用于与各种外围器件进行通信。这种通信方式采用三线连接 ,全双工同步数据传输 ,具有连线少、速度快、可靠性高等特点。相控阵雷达的波控系统不仅控制雷达阵面组件单元的相移工作 ,还需对其工作状态进行监测。SPI技术在波控监测中得到了广泛应用 ,在子阵和组件单元间通过SPI实现了高速、实时、可靠的数据交换 ,在子阵级完成对组件的监测 ,从而实现波控系统对整个阵面的监测

SPI(Serial Peripheral Interface) technique is u sed for communication with various peripheral devices. This kind of communicatio n mode employs three-wire connection and full duplex synchronous data transmiss ion. It has the features of less link, fast speed, high reliability and etc. The beam steering system of the phased array radar not only controls the phase shif t of the modules on the array of radar but also monitors their operation state. SPI technique is widely used in the beam steering, and can realize monitoring on the whole array be the beam steering system through high-speed, real-time, re liable data exchange between sub array and modules, and monitoring on the module s at the sub array level.
