【摘要】 针对GPS接收机的抗干扰问题,以自适应阵列天线为研究对象,提出了一种高动态GPS接收机的自适应抗干扰递推算法。算法是基于功率倒置方法,并在干扰方向加微分约束,经推导得出一种微分递推算法。仿真结果表明,相比一般的导航抗干扰算法,此算法不仅可在干扰方向上加宽零陷宽度,且由于采用递推,其收敛速度有显著提高。更多还原

【Abstract】 A recursive adaptive interference suppression algorithm is proposed for high dynamic global positioning system receiver. Based on PI( power inversion) approach,this new method adds derivative constraints to the interference direction of arrival( DOA) and derives a derivative recursive algorithm,which achieves wider null in the jamming direction and higher speed than traditional navigation interference suppression algorithms.更多还原
