摘要
针对传统的功率倒置算法应用在卫星信号接收时,不能在有用信号方向上形成主波束,不具有提高信噪比的功能,提出一种新的波束形成零陷算法,提高了该功能。通过软件仿真验证,结果表明提出的新算法克服了功率倒置算法在有用信号方向不能形成主波束的不足,不仅能在干扰方向形成更深的"零陷",而且具有更高的输出信噪比。
When applied in the reception of satellite signal,the traditional power inversion arithmetic can＇t form lord beam in the direction of useful signal and raise the value of SNR,which are concerned by many researchers.These questions were investigated in this paper and a new directive beam formation algorithm was put forward to improve these.By verified on the simulation,the result shows the new directive beam formation algorithm overcomes the shortage which can＇t form the lord beam in the direction of useful signal based on the power inversion arithmetic.It can form the deeper nulling in the jamming direction and get the higher value of SNR.
