摘要
针对信源线拟合算法(SLFM)受限于均匀线性阵列(ULA)的缺点,提出了一种改进算法。该算法通过曲线-直线变换,将非均匀线性阵列(NLA)变换为均匀线性阵列。仿真结果表明,新算法在保持原算法估计精度的同时,突破了均匀线性阵列条件的限制。
This paper proposes an improved source line fitting method (SLFM) , which can work on non - uniform linear array (NLA) ,while the original algorithm is designed for uniform linear array(ULA). It is demonstrated that the improved algorithm converts NLA to ULA by a curve - line transformation. Computer simulation shows that it overcomes the restriction of ULA and performs the same accuracy as SLFM.
