多面阵雷达是一种利用多个两维相扫阵面协同工作的相控阵雷达,具有复杂的时序控制需求。针对该需求,提出了一种时序控制器设计方案。该方案利用现场可编程门阵列(Field Programmable Gate Array,,FPGA)的灵活性和时序准确性,结合参数化设计,实现了Peripheral Component Interconnect express(PCIe)总线接口、通用异步收发器(Universal Asynchronous Receiver/Transmitter,UART)接口、时序产生等功能,很好地保证了复杂时序的统一调度。实际工程应用表明,该时序控制器设计合理,具有良好的稳定性和可测试性。
