- W1999751397 abstract "In this paper, the Weighted Subspace Fitting (WSF) method using Artificial Bee Colony (ABC) algorithm is applied to the problem of estimating the direction-of-arrival (DOA) and the Doppler frequency of multiple signal sources impinging on an antenna array simultaneously. The extended observability matrix containing the angle and frequency parameters is established using state-space model. The WSF method is used to estimate the parameters accurately and convert the problem from parameter estimation to a nonlinear multidimensional function optimization. Then artificial bee colony algorithm is applied to optimize the function and estimate the DOA and Doppler frequency. The proposed method reserves the asymptotic unbiased estimation of the WSF method and reduces the computational burden of calculating the solution. Besides, the estimated parameters can be paired automatically." @default.
