摘要
本文提出了一种近场源距离、频率及到达角 (DOA)三维参数联合估计算法 .该算法不需谱峰搜索且各参数自动配对 .由于算法使用了四阶累积量 ,所以适用于任意加性高斯噪声环境 .
A computationally eficient algorithm for jointly estimating range DOA and frequency of near field narrowband source is presented.Without spectral peak searching and pairing among parameters,it can be employed to arbitrary Gaussian noise environment since fourth-order cummulants are employed.Finally,its performances are confirmed by computer simulations.
