| 摘 要： | 为了找到一种适合于全球定位系统(GPS)接收机抗压制性干扰的方法,在介绍自适应数字波束形成的基础上,研究了直接矩阵求逆(SMI)和GS自适应算法的基本原理,在GS算法的基础上进行了改进,在均匀线阵中对各算法进行仿真,比较了各算法的优缺点,在运算量小和抗干扰性能稳定的前提下,认为改进的GS算法是适宜于工程实现的一种好方法.

| Abstract: | This paper put forward a new adaptive anti-jamming algorithm-Improved Gram-Schmit (IGS) algorithm. Using line antenna array model, this paper compared the new algorithm with two conventional adaptive anti-jamming algorithms: Sample Matrix Inversion (SMI) adaptive algorithm and Gram-Schimit (GS) algorithm. In multi-interference circumstance, the new algorithm has balanced and stable performance. Simulation also shows its computation burden is lower, and engineering implementation process would be easier. |
