FPGA技术在变极化系统中的应用

Applications of FPGA Technologies in Polarization Radar Systems

通过对变极化系统抗干扰器的原理分析,提出利用现场可编程门阵列(Field-Program-mable Gate Array,FPGA)技术控制发射信号源相位的方法,并在QuartusⅡ工具中进行仿真实验。结果证明,该方法测量精度较高,最后对该方法的使用场合作了讨论。

This paper firstly gives an introduction of the concept of variable polarization system and basic theory of anti interference of variable polarization system . Then, this it gives the application method of using FPGA technology into Signal phase control after the analysis of the principle of polarization converter. At last the result proves a higher precision of the application method which based on the simulation of Quartus Ⅱ tool and gives a simple analysis of the quality of application method we focused on.
