摘要:

全球移动通信(Global System for Mobile communication,GSM)信号已经被很多文献证明可以作为外辐射源雷达的机会照射源信号,但是在以往的研究中主要考虑抑制主基站的直达波和多径干扰.而实际上,GSM辐射源雷达不仅受到主基站的干扰,还受到其它同频基站的干扰.为了消除主基站干扰,同时抑制其它同频基站的干扰,本文提出首先利用扩展相消算法(Extensive Cancellation Algorithm,ECA)在时域上消除主基站的干扰,然后利用基于最差性能最优准则的稳健自适应波束形成在空域上对其它同频基站干扰进行抑制.最后仿真分析表明本文提出的杂波抑制方法的有效性.

Abstract:

The application of GSM(Global System for Mobile communication) signal as opportunity source of passive bistatic radar has been demonstrated in many references.However,in the early research,only the suppression of direct signal and multipath from the host station is considered.In practice,GSM based passive bistatic radar receives interference not only from the host station but also from other station with the same frequency.In order to suppress the interference from the host station as well as the one from other stations,this paper proposes that the host station's interference is firstly cancelled using ECA(Extensive Cancellation Algorithm) algorithm,and then the other stations' interference is suppressed by a robust adaptive beamformer based worst-case optimization.In the end,simulations verify the availability of the proposed method.

Key words: passive bistatic radar, global system for mobile communication (GSM) signal, disturbance suppression, robust adaptive beamformer
