摘要
自适应天线与跳频技术相结合可进一步提高系统的抗干扰性能。对跳频系统中快速跟踪干扰的抑制 ,采用基于特征空间 (ESB)自适应波束形成算法可提高波束的收敛速度 ,并与空间平滑技术相结合 ,可有效抑制与期望信号相关的快速跟踪干扰。计算机仿真结果证明了该方法的有效性。
The interference-resistance ability can be improved by the combination of adaptive antenna with frequency-hopping (FH) technique. For the problem of suppressing fast following jamming in FH system, a new jamming rejection method is proposed, which combines eigenspace-based adaptive beamforming with the technique of spatial smoothing. The simulation results show that the proposed method not only improves the convergence speed, but also effectively suppresses the coherent fast following jammer.
