| Abstract: | 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. |

| Keywords: | array signal processing DOA estimate range estimate frequency estimate fourth-order cumulant |
