摘　　要：自适应调零抗干扰技术可以很大程度改善导航抗干扰性能,也是目前导航抗干扰技术中不可或缺的,其研究意义重大。首先介绍功率倒置算法,并推导验证功率倒置算法基于参考信号最小均方误差模型和线性约束最小功率模型的统一性;最后提出一种同心圆形阵列,并仿真对比Y形阵,发现功率倒置算法下同心圆形阵列模型具有更优秀的抗干扰性能。The adaptive nulling anti-jamming technology can greatly improve the navigation anti-jamming performance.It is also indispensable in the current navigation anti-jamming technology.Firstly,the power inversion algorithm is introduced,and the unity of the power inversion algorithm based on the minimum mean square error model of the reference signal and the linearly constrained minimum power model is derived.Finally,a concentric circular array is proposed,and the Y-shaped array is compared with the simulation.It is found that the concentric circular array model under the power inversion algorithm has better anti-interference performance.
