【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]:Global System for Mobile communication signal has been proved to be an opportunistic source signal for external emitter radar in many literatures. However, in previous studies, the suppression of direct wave and multipath interference of the main base station has been mainly considered. In fact, GSM emitter radar is interfered not only by the main base station, but also by other same frequency base stations. In order to eliminate the interference of the main base station and suppress the interference of other common frequency base stations, the extended Cancellation algorithm is proposed to eliminate the interference of the main base station in time domain. Then robust adaptive beamforming based on the worst performance optimal criterion is used to suppress the interference of other co-frequency base stations in airspace. Finally, the simulation results show that the proposed clutter suppression method is effective.
