摘要
针对军事和民用领域持续增长的定位需求,提出基于升空大规模多输入多输出(Multiple-Input Multiple-Output,MIMO)平台的波束域无源定位方法,该方法能够充分结合升空平台的空地视距(Line of Sight,LoS)传输特点和大规模MIMO技术的高空间分辨率优势,通过挖掘升空大规模MIMO平台接收信号的波束域相关特征实现目标角度和位置信息的低复杂度估计。数值仿真结果表明,所提方法能够实现接近亚米级的定位精度,从而验证了所提方法的有效性。
Aiming at the growing demand of location in both military and civil field,a new passive positioning method based on airborne massive MIMO(multiple-input and multiple-output)platform is proposed.This method can fully combine the characteristics of air to ground LoS(the Line of Sight)transmission of airborne platform and the advantages of high spatial resolution of the massive MIMO technology,and realize the lowcomplexity estimation of the target angle and location information by mining the beam-domain correlation characteristics of the received signals of the airborne massive MIMO platform.Simulation results indicate that the proposed method can achieve the positioning accuracy close to sub-meter level,thus verifying the effectiveness of the proposed method.
