摘要
对于阵面规模小的相控阵雷达,波束控制系统为了减少设备硬件量,满足快速波束变换的要求,采用集中式控制模式,查表计算的方法来实现波束控制码的运算和状态码的控制。设计中DSP计算查找波控运算基码,FPGA根据基码按阵面排列顺序并行计算各个单元的波控码,有效地降低了波束转换时间。采用DSP和FPGA相结合的工作方式,运算速度快、编程灵活、调试方便,对于分布式波束控制的设计也具有一定的参考性。
For the phased array radar is small, the beam control system in order to reduce the amount of hard- ware equipment, meet the requirements of fast beam transformation, the use of centralized control mode, the look- up table calculation method to realize beam control code operation and status code control. Design calculation of wave control arithmetic based search DSP code, FPGA code base according to the array according to the order of parallel computing in each unit of wave control code, effectively reducing the beam conversion time. Using DSP and FPGA combination of work style, fast operation speed, flexible programming, debugging convenient, also has certain ref-erence for the design of distributed beam control.
