摘　　要：射频干扰会严重影响GPS接收机的工作,导致接收机无法跟踪锁定有用信号,从而无法精确导航定位。而自适应天线是一种有效的抗干扰措施。文中分析了GPS接收机在接收信号的过程中易受到干扰的原因,提出了一种有效的自适应抗干扰算法,并在A ltera公司的Stratix系列芯片中实现了该算法。Radio-frequency interference will cause severe degradation of GPS receiver, and adaptive antenna is an effective anti-jamming measure for GPS receiver. In this paper, we find the reason why the GPS receiver is easy to be interfered by various interfering signals. Then we put forward an algorithm to solve this problem. Finally we choose Stratix chip to realize this algorithm.
