摘要
论述了多辐射源波长与方位同时估计问题。建立了宽频段阵列信号模型,给出了波长与方位的最大似然估计及其全局优化算法,计算机模拟结果证实了算法的有效性。
This paper proposes an approach for estimating wavelength and azimuth of multiple narrow band sources over a wide range of frequency.Array signal model is constructured and ML estimator with its global optimization algorithm is presented.Simulation results show that the proposed algorithm is valid.
