| 摘 要： | 本文提出一种基于三阶循环矩的近场源二维参数估计方法.该方法以均匀线阵为接收传感器阵列,通过构造三个三阶循环矩矩阵估计出近场源的方位角和距离参数,利用循环统计量去除加性噪声,通过预校准法消除乘性噪声,适用于乘性噪声或乘性噪声和加性噪声共存背景下的二维近场源定位.仿真实验验证了该方法的有效性.

| Abstract: | A method for estimating two dimensional parameters of near field sources based on third-order cyclic moment was proposed.Based on uniform linear array and third-order cyclic moment,the algorithm constructed the three matrixes of third-order cyclic moment.Then it estimated the bearing and range parameters of near-field sources.The algorithm removed additive noise and multiplicated noise by cyclic statistics and pre-calibration respectively,so it can work well in multiplicated noise environment or multiplicat... |
