| 摘 要： | 本文研究利用波束形成技术与跳频技术相结合,在存在宽带阻塞干扰以及跟踪干扰时,将信号与干扰在空域进行分离,提高跳频系统的抗干扰性能。指出利用空间平滑不仅可以有效抑制相干跟踪干扰,而且提高了波束的收敛速度。仿真结果证明了该方法的有效性。

| Abstract: | This paper discussed the combination of adaptive beamformer(ABF) with frequency-hopping(FH) system to discriminate the signal and interference in spatial domain,then developed the FH-system's anti-jamming performance.Using the technique of spatial smoothing not only can effective suppress the coherent following jammer,but also can inprove the beamformer's convergence. Computer simulation results demonstrate the effectiveness of the proposed method. |
