摘要 针对近场三维参数估计方法计算量大的问题,提出了一种近场源的方位角、仰角和距离的三维参数估计方法。该方法利用在x-z平面十字阵列的结构特点和二阶统计量,估计信源的方位角、仰角和距离参数。将三维参数估计问题转化为多个一维搜索问题,从而减少了算法的计算量,并且无需参数配对,具有估计精度较高的优点。仿真实验表明,在信噪比大于0时,该方法能有效估计近场源的三维参数。 Aiming at the problem that the computing burden of near-field three dimensional parameters estimate methods is huge, a method for estimating three dimensional parameters of near field sources based on second sta- tistics is proposed. The presented algorithm uses the cross-array in x-z plane and second statistics to estimate bearing-elevation-range parameters of near field sources. Using second statistics and changing the three dimen- sional problem into one dimensional parameter estimation, the method has the merits of low computational burden and good estimate precision. It also does not require parameters pairing. The simulation results show that the algorithm can estimate the three dimensional parameters of near field well when SNR （ Signal to Noise Ratio） is higher than 0
