摘要
在GPS接收机的抗干扰领域,空域滤波算法(自适应调零)是目前应用最广泛的方法,空-时二维自适应滤波算法是目前最先进的方法;而在抗干扰接收机的天线阵型中,线形阵和圆形阵是比较常用的2种阵型。介绍空域滤波和空-时二维自适应滤波这2种算法的基本原理,用对2种算法做了仿真,并做性能分析;同时对空域滤波应用线形天线阵和圆形天线阵进行仿真,并做出性能分析,最后得出结论。
In the field of GPS anti-jamming receivers, spatial filter is the most popular algorithm, space-time adaptive filter is the most advanced algorithm. At the same time, linear antenna array and circular antenna array are two usual arrays in the array-choosing of GPS anti-jamming receivers. This paper introduces the theory of spatial filter and space-time adaptive filter, simulates the two algorithms, and analyses performance of them. This paper also makes simulation on linear antenna array and circular antenna array, and analyses performance of them, at last makes conclusion.
