【摘要】：利用特殊極化敏感陣列極化域的旋轉不變性,提出了一種基于交叉偶極子-磁環(huán)天線(COLD)陣的近場源閉式定位算法.與現有方法相比,該算法無需高維搜索和高階累積量運算,也無需參數配對,計算效率高;無需陣列具有對稱結構,陣列孔徑利用率高.COLD陣方法無需高階項舍棄,與交叉偶極子陣方法相比,也不涉及接收模型的近似假設,性能更優(yōu)越并可實現無偏定位.計算機仿真驗證了所提算法的有效性.
[Abstract]:Based on the rotation invariance of polarization domain of special polarization sensitive array, a near-field closed source localization algorithm based on cross dipole-magnetic ring antenna (COLD) array is proposed. Compared with the existing methods, the algorithm does not require high-dimensional search and high-order cumulant operation, and also does not require parameter matching, so it has high computational efficiency. There is no need for the array to have symmetric structure and the array aperture utilization ratio is high. Compared with the cross dipole array method, the cold array method does not need to abandon the high-order terms and does not involve the approximate assumption of the receiving model, so the performance is better and the unbiased localization can be realized. The effectiveness of the proposed algorithm is verified by computer simulation.
