摘　　要：针对传统导航抗干扰算法权值求取运算量大,工程实现困难的问题,该文基于最小功率输出准则,利用最陡下降和递归最小二乘算法原理,将传统导航抗干扰算法权值求取过程中的矩阵求逆运算转换为权值迭代运算,并在权值迭代更新过程中进行了归一化处理,提出归一化迭代导航抗干扰算法。该文通过仿真分析和实验验证的方式验证了算法的抗干扰性能,仿真和实验结果表明,该文算法抗干扰能力强,算法运算量较小,易于工程实现。Aiming at the problem of large computation and difficult engineering implementation of traditional navigation anti-interference algorithm,based on the minimum power output criterion and the principle of steepest descent and recursive least squares algorithm,this paper converts the matrix inversion operation in the process of weight evaluation of traditional navigation anti-interference algorithm into weight iteration operation,and carries out normalization processing in the process of weight iteration update.A normalized iterative navigation anti-jamming algorithm is proposed.In this paper,the anti-interference performance of the algorithm is verified by simulation analysis and experimental verification.The simulation and experimental results show that the proposed algorithm has strong anti-interference ability,small calculation amount and easy engineering implementation.
