| 摘 要： | 提出一种利用FPGA实现相关干涉仪测向算法的方法,给出了测向系统的结构和组成框图,并详细介绍了FPGA内部模块的划分及设计流程,最后结合实际设计出一种实现方案,并讨论了该方案在宽带测向中较原有实现方式的优势。为了使算法更适于FPGA实现,提出了一种新的相位样本选取方法,并仿真验证了该方法与传统方法的等效性。

| Abstract: | A method to realize correlation interferometer direction finding algorithm by FPGA is given.The structure and com-position of direction finding system is given,meanwhile the division of FPGA modules and design flow are introduced in detail.Fi-nally,according to practical application a design scheme is given.And the advantage of this design in broadband direction finding is brought forward.In order to make the algorithm more suitable for FPGA implementation,a new method of selecting the phase sample is proposed and simulation verifies that it is equal to traditional method. |
