摘要
针对GPS接收系统的空时自适应抗干扰技术,提出了一种基于原型自动编码机的空时自适应算法.通过对空时自适应和算法的建模,研究了该算法的性能.系统仿真表明,该算法不仅能抑制大于阵元个数的多个宽、窄带干扰,而且有很好的收敛性,对工程实践具有一定的指导意义.
According to the technology on space‐time adaptive anti‐jam of GPS receiver system ,a new GPS space‐time adaptive algorithm based on prototype autoencoder has been proposed .By modeling space‐time adaptive processing and this algorithm ,the anti‐jam system performance has been studied .Simulation re‐sults show the number of wideband and narrowband interferences can be suppressed by this algorithm , w hich has been proved to enjoy good astringency and has direct engineering practice value .
