摘要
目前FPGA是开发波束控制系统的首选控制芯片,但FPGA在计算浮点数据时存在耗时长并且资源占用大的问题,对波束控制算法的实现存在一定限制。基于此提出一种查表与FPGA计算相结合的优化型波束控制算法,以8×8矩形相控阵天线为控制对象,详细介绍了该优化型算法以及FPGA算法模块的逻辑设计,优化型算法降低FPGA资源占用率,节约系统功耗的同时又规避了FPGA难以计算三角函数的问题,最后基于Vivado/Xsim搭建仿真平台,仿真与测试结果证明了该方案的正确性和高效性。
At present,FPGA is the preferred control chip in the development of beam control system,but FPGA has the problems of long time consuming and large resource occupation in computing floating-point data,which limits the implementation of beam control algorithm.Based on this,this paper proposes an optimized beam control algorithm which combines look-up table and FPGA calculation.Taking 8×8 rectangular phased array antenna as the control object,the optimization algorithm is introduced in detail.Finally,a simulation platform is built based on Vivado/Xsim.The simulation and test results prove the correctness and efficiency of the scheme.
