摘要
本文基于一种对导航信号当中产生抑制现象的干扰盲波束形成的算法,以免因为干扰因素的存在而造成造成信息接收过程出现问题,最大化的增益GNSS信号,增强其准确性和有效性。以该方法为基础不需要事先确定GNSS信号来波方向,阵列误差稳健。实测数据表明,在多种干扰场景下,所提方法均能干扰抑制能力均良好,相比于SCORE方法、功率倒置法,本研究所提方法在抑制干扰的同时,能保证输出中GNSS信号信干噪比最大化,稳健性很强。最后提出对卫星接收器的维护措施。
This paper presents a blind beamforming algorithmto suppress interference in navigation signals'which can ensure that interference is suppressed and the GNSS signal has the maximum gain.The proposed methiod needs no prior knowledge of thie di-rection of arrival of GNSS signals'and the array error is robust.The measured data show that the interference suppression ability of the proposed method is good under various interference scenes.Compared with the SCORE method and the power inversion method,the proposed method can ensure the maximization of the signal to noise ratio of the GNSS signal in the output,and the ro-bustness is very strong.Finally,the maintenance measures for the satellite receiver are put forward.
