摘　　要：相控阵雷达波束控制系统的性能极大地影响雷达功能的发挥,文章采用基于现场可编程门阵列(field-programmable gate array,FPGA)芯片实现波束调度,具有速度快、可靠性高、控制灵活及便于扩展等特点;然而FPGA芯片不具备浮点运算功能,无法进行实时计算。文章将查表法和实时计算法相互结合,取长补短,规避了FPGA无法完成浮点运算的缺陷,又节约了码表存储的内存空间,具有广泛的工程应用前景。The performance of the phased array radar beam control system greatly affects the performance of the radar function. The implementation of beam scheduling based on field-programmable gate array(FPGA) chips has the characteristics of high speed, high reliability, flexible control and easy extension. However, FPGA chips do not have floating-point operations. Functionally, it is unable to perform real-time calculations. The combination of look-up tables and real-time calculation methods can complement each other, avoiding the inability of the FPGA to complete the floating-point operations, and saving the memory space of the code table storage, with a wide range of engineering applications.
