摘要

针对GPS抗干扰问题,常用手段是在信号处理系统中采用自适应调零算法来实现抗干扰。结合该算法文中给出了一种信号处理系统的硬件实现方案。首先概述GPS自适应调零天线的系统结构,然后给出信号处理系统的硬件设计思路及其功能模块的实现,最后通过实测数据验证硬件模块可以满足自适应调零算法的要求。%For GPS interference problems,the common method in the signal processing system is to achieve interference using the adaptive nulling algorithm.This paper presents a signal processing system hardware implementation scheme together with an algorithm.First,the architecture of the GPS nulling antenna is described,then the paper gives the signal processing hardware design ideas and implementation of functional modules.Finally the results of the measured data show that the hardware modules can meet the requirements of the adaptive nulling algorithm.
